I think I'd be good at plugins....while I'm here may as well type out my ideas.
Have WorldEdit only to be able to use WorldGuard. That way we can set the spawn region, keep it grief free, stop mobs from spawning, disable pvp, etc.
I think there should be a /home.... Essentials has that auto bundled in it. Just have to mess with the config. I know you can choose how many homes normal players can set, donaters can set, admins, etc. So you could have 10 homes, or just 1. Whatever number. (or none )
AntiCheat is a good non-cheating plugin, but I need to do some research for a plugin that keeps track of who breaks what block, or just get GriefPrevention working. (people set regions within a certain amount of blocks, and that area is theirs)
Something like Lockette...I'm finding out what the plugin that uses the "magical spells" to look chests and things is now.
GroupManager *once you get it working* just makes setting perms easy, Also finding out how to make it so after "x" amount of hours playing the player gets trusted,. Makes it so that trolls/griefers can't just get on and do stuff. People have to take time, and most trolls won't.
That's about it from what I'm thinking about right now.
