Trying to answer random questions from above:
- If you die, you restart at the world spawn point. You can move it with a third party program (Mineedit?) but otherwise you will always respawn at the same point. I think you always lose your armor, but your inventory may remain there for a few minutes if you hurry back to the spot you died. All buildings in the world should remain the same.
- If you're in a snowy world, currently the whole world will be snowy. Hopefully this changes in the future, as well as more biomes being added (like swampy etc.) (fake edit, this was already answered)
- Hopefully the server supporst IP bans, then we'll be set. :lol
- If you get hurt from falling, if it's like Notch's server you can just set the difficulty to peaceful and you will recover HP (same if you get caught on fire by lava I think).
What's new in the latest versions?
*edit* Oh, inventory and especially chests resetting on logout will be a huge pain. I wonder if signs will work. Also, I'm almost certain the furnace DID NOT work when I was on the multiplayer server, does anyone know if he fixed that?
