Nice dude, I'm just on it now. Gonna make a little underground base for myself I reckon, but chances are anything I make won't be saved if we end up setting it to Peaceful mode or whatever.

EDIT : Also I forgot, Creative Mode is just like, 1 click destruction, and your Inventory is everything you'd ever need in the game.

If I start playing hard now, can we keep the stuff we built in Creative Mode when the server goes to normal Peaceful Mode? I wanna get started on a little project before it gets difficult to mine without 19 other people fighting over materials and taking all your ore.

EDIT : Okay upon further inspection, you can totally change from Creative to Survival Mode. The thing is though, the game is in Beta at the moment, but the full game comes out at the end of November.

Also whilst digging around, the first cave I found had structures in it, but they were really weird. It's like all the tracks were facing the wrong directions, and there were wood supports and stuff. I don't think they were made by a player, but it was just creepy.

EDIT : I just realised that when the new Minecraft comes out, you'll have to update the server to the newest version, so the maps will be lost (because there is a new environment). So I probably won't bother until the update.
