If you do make a server make sure it has:
1. A whitelist feature - So no idiot can just come in and distroy something.
2. Disable Wood burning - (Possibly let netherrack burn if possible)
3. Peacefull and mobs on. OR Easy and mobs on.
4. Chest Protect, preferalby LWC.
5. Warping (/home, /spawn, /home invite player, /home set, home uninvite player, /home player, etc.)
All that would make a great server.
Optional:
Big Brother - to keep track of everything that happens. Records who distroyed what block where and who removed/placed in whos chest where.
1 Free iron pickaxe for people when they first come - This would help new players start their base faster. But don't give them moer than one and NEVER diamond!
So that's my idea. I coudn't set up a server or anything like that though. And I have my own commonly used servers so don't expect me to be there.
