I believe the climate bands really only apply to the general annual temperatures for that latitude, and not the rainfall. It's possible to have warmer or colder chunks mixed in--for example, the temperate bands can have pockets of cooler/warmer climates. Elevation also affects climate--the higher you go, the colder it gets. 
Rainfall determines whether a particular region is likely to be lush plains/forest or a desert. In the temperate bands, the areas with high rainfall will have better soil quality, and tend to support more forest, while the areas with less rainfall will be deserts or regions with low soil fertility. In the tropical climate bands, high rainfall tends to result in jungles, while low rainfall produces deserts and savannahs.

The percentile readings can be low, but the main thing to watch is the general reading description: Very Poor, Poor, etc. Typically it's best to dig at Decent or better, but if what you're looking for is rare or the best lead you have is Poor/Very Poor then it doesn't hurt to try digging at one of those readings.
When it comes to bronze, you can also buy tin, bismuth, and zinc from Commodities traders, if you happen to be a few ore short of what you need. Panning bony soil can also yield gold/silver nuggets that can be turned into a black bronze tool or two.

Generally, it's best to wait until a stable release before trying to update old worlds, but even with stable releases it's a good idea to make a world backup anyway in case something goes wrong.
 
This is also an option. You could also try updating an older world to see what happens, but make sure you back up the world first, as there is more likelihood of things going wrong on unstable game versions.
 
Chunks that have already been generated won't contain new blocks like the new berry bushes. You'll need to either head to new areas of the world map to discover the new stuff, regenerate old chunks via command, or start a new world.

According to the wiki, chickens need to eat at least 3 portions of feed before they can mate. My general strategy though is to just feed them once a day while they are filling the nest and then once every 2-3 days while they are incubating the eggs.
 
Bighorn sheep are typically found up in the hills and mountains, typically in regions that a little cool and on the dry side, and not heavily forested. Mouflons(added in 1.22) spawn in the warmer lowlands, but not in dense forest.
Musk ox spawn in the arctic, so you will have some long walks and a lot of work ahead of you if you want to domesticate these. Or I mean...just use the creative menu to spawn a pair in and pretend you purchased them from a trader.

Welcome to the forums!
I think development has been progressing quite well, but I don't expect 1.22 stable to be ready by the first of April. There are still several bugs to swat and some of the content still needs to be polished, like procedural dungeons and berry bushes, if those features are going to be fully added in the stable release.

An in-game week is seven days. An in-game month will vary, and is nine in-game days by default. The processing time for steel will always take about an in-game week, to my knowledge, and does not scale with the month length.

Welcome to the forums!
From the rc1 news post:
Basically, if the world was created in a 1.22-rc version, it's probably fine to keep playing until stable. If a world was created in a 1.22-pre version, it's likely to have issues upgrading and not recommended for continued play. Worlds created in prior stable versions shouldn't be upgraded to 1.22 until the stable version releases, though more adventurous players can still give it a try provided they make a backup of the world first.

I think the answer to most of the questions is...it depends on the server. Some will use mods, some will not. Anego servers don't support mods at the moment, so servers purchased from Anego Studios will always be vanilla. Server etiquette will depend heavily on what kind of players inhabit the server and how well the server ruleset is actually enforced; as a general rule servers that encourage PvP will have a lot more griefing/aggravating behavior due to the nature of PvP gameplay itself.
For servers in general? Not really. Each server will have its own set of rules on how players are expected to behave, and some will be more strict than others.
As I understand it though, larger servers tend to have more problems with the spawn area getting picked clean, and while they may have plans in place to help new players out(like admin teleporting them to a fresh area) you may have better luck with a smaller server.
Probably depends heavily on what kind of players play on the server and the general server rules. If land claims are allowed, other players(outside of admins) shouldn't be able to mess with your stuff as long as it's in a claimed area, to my knowledge.
As to whether players settle close together or further apart...depends. Those looking for a more cooperative game will be inclined to settle closer together, if not share a base, while others may prefer to have their own space. Roleplaying servers may have special rules in place over who can settle where.
This I'm not sure, but most should have the settings listed alongside the rules on Discord or a server advertisement or something.
 
It's another case of it depends on the server in question. Some prefer to handle it as a group activity. Some probably don't care. Some reset the story locations periodically so that everyone can have a chance to do the content.
 
Depends on the server, but unfortunately most seem to rely heavily on Discord for communication and information about the server.
 
You don't have to disable your mods before joining a server, to my knowledge, unless you're trying to join a server hosted by Anego, in which case you may need to disable the mods yourself. Otherwise, I don't think it's necessary, but it's something I would recommend, since having mods enabled clientside can sometimes cause strange issues when playing on modded servers(had it happen a time or two).
As a general rule though, the required mods will be downloaded and enabled automatically when you connect to the server. Generally, the mods installed on the server will be posted somewhere, either in the server advertisement or on Discord.
Not really, but don't forget that if you can't find a server that strikes your fancy, starting your own is always an option. Personally, when it comes to multiplayer games, I prefer to play with people I'm already friends with, or at least familiar enough with to have an idea of their general personality. It cuts down on a lot of issues that tend to be common when dealing with the general public.

Welcome to the forums and the game!
You're not really doing anything wrong, but I will note that terrain and biomes in Vintage Story work in a more realistic fashion. That is, biomes are determined by the latitude and local rainfall. The default start is the temperate zone, so going north will take you to taiga and polar regions, while heading south will take you to the warmer tropical regions around the equator. Areas without much rain will be deserts and gravel plains, while areas with more rainfall are more likely to have forests and lush plains. By default the polar-equator distance is 100k blocks, meaning you'll need to travel around 10-20k blocks or so before you really start to see much of a change in the climate.
I will note though that you can always change certain settings at world gen to get different experiences. The option to change the starting climate can be found under the "Player spawn and death" settings tab. Under the "World generation" tab, you can change the polar-equator to be bigger or smaller, as well as change the global temperature and rainfall to get hotter/colder or drier/wetter worlds. Changing the "Climate distribution" option to "Patchwork" instead of "Realistic" will result in a more Minecraft-style world, where cold and hot biome types spawn in random patterns and no longer follow latitude rules.

Sounds like a bug to me. I think the tree grafts are mainly meant for creating mixed-variety fruit trees, but the concept should work the same for the single variety trees.

It's under "Small water wheel". You'll need a hammer, one axle, and two small iron 4-way hubs. The hammer goes on top of the axle, and the hubs on either side. After that, it's a matter of placing the resulting water wheel part down next to the rapids you wish to build on, and then following the crafting prompts it gives you after. Fair warning--you'll need a lot of beams, boards, and resin, as well as several bronze or better nails.

Navigate to your VintagestoryData folder--this is where your game saves and mods and everything is stored. There will be a folder labeled Playerdata within. Open that folder and look for the playersbanned.json file. All you have to do from there, I think, is open that file, remove your name from the list, and you should be able to rejoin your world.

Welcome to the forums and game! Which version are you playing on? It's a known bug for 1.22.0-rc1.
https://github.com/anegostudios/VintageStory-Issues/issues/8571

Try reducing the respawn radius from world spawn. By default, I believe it's 50 blocks.
/worldconfig spawnRadius 0 might fix it.
You might also trying standing exactly where you want the spawn point to be and use the command /serverconfig setspawnhere That may work as well.

Maybe. It depends, I think, on whether or not the chunk was loaded. Otherwise, fired projectiles have the same expiration timer as dropped items, to my knowledge. 
Personally, I wouldn't really expect them to be there, since generally I assume that things that have been sitting like that for a while have despawned. However, it doesn't hurt to check. Worst case scenario, you can always "find" it in the bushes or behind a tree.

Welcome to the forums! You could try a mod like this one and see if that solves the issue: https://mods.vintagestory.at/naturalspawns
There's also mods to adjust what light level that monsters can spawn at, and a mod or two to stop monsters from spawning on the surface entirely(outside of temporal storms), though I'm not sure how well the latter works regarding the story.
The pure vanilla solution is to turn rifts off, and temporal storms as well potentially, since conventional spawn rules are ignored during temporal storms. That should cut down on most of the spawns, at least.

I don't think there's a command for it, but you could probably make a mod that changes the maximum room/greenhouse size, if such a mod doesn't already exist. Or you can probably alter the game files directly to accomplish the same thing, although I don't really recommend doing that since that can be tougher to fix if things break, as well as be easily overwritten when updating the game.

It shouldn't break, as long as it's vanilla. If it's modded, especially heavily modded, then it becomes a lot more iffy. I'd still make a backup of the world though, just in case something does go wrong.

Welcome to the forums! Posting underneath a spoiler tag to avoid spoiling the story for those who haven't reached that point:

Welcome to the forums! There is currently no way to rotate tables, to my knowledge.
 
The wrench is useful for rotating machinery-related blocks and chiseled blocks, but otherwise limited in which blocks it can rotate. The blocks it can rotate should be listed on the wrench's tooltip text, and outside of that the blocks that can be rotated should have an interface prompt showing they can be rotated via wrench and the appropriate key/click combination to do so, provided such interface prompts are enabled in the settings.

Right, but you need more than 3-4 berry bushes to keep you alive. That many bushes will, on average, give a player 12-16 berries, which is enough for one day and that's about it.
 
This is true for most foods in Vintage Story. Plants take time to grow, as does livestock. Wild animals often respawn relatively quickly though, which is one reason hunting is more reliable. Like @MKMoose said, you'll want to scout a fairly wide area if you're relying on hunting and foraging for your food. Also keep in mind that most food has a shelf life--you don't want to collect more than you can eat in a couple of days unless you have some way to preserve it.
 
Clay is usually difficult to spot until you learn what it looks like. If the sides are visible there is a noticeable difference in color between the clay and surrounding dirt; viewed from the top it's a little harder to spot as the patchy grass on top of the clay blends in to surrounding grass, but there will be bits of clay color peeking through. Red clay is the more common find, occurring wherever there's enough rainfall. Blue clay tends to be found around sea level, often by bodies of water, and like red clay also requires enough rainfall to form deposits. Fire clay is the rarest variety, spawning only in bauxite or sometimes underneath black coal/anthracite veins.
If you're having trouble finding a deposit, you might try your luck with cracked vessels. Sometimes those contain small amounts of clay.

No lead poisoning. The only difference currently is the materials used to create the solder. If the player doesn't have tin to spare, or lacks a source of tin entirely, they can opt for silver solder instead if they have a bit of silver lying around.

Welcome to the forums!
The normal method is to use a temporal gear--do note these have limited respawns, so you may need to refresh the spawnpoint once in a while, depending on how often you die. You should also be able to use the command /serverconfig setspawnhere to permanently set the world spawn at your location. Or you could opt for a mod that changes spawn via bed, similar to the other block game. https://mods.vintagestory.at/simplebedspawn

Welcome to the forums(and the game)! My first thought is that it's probably XSkills, but it's hard to say for sure. The easiest way to figure it out is, as @Zane Mordien said, go into the mods folder for that particular server and see what's there. @RationallyParanoid also has a good point in that it might not be a mod that's causing it, but rather a choice of class.
