While we are suggesting things, I think more worlds (Possibly by rank) would be good. As in a guest world (Everyone can access), a member world (Member+) and a trusted world (Trusted+) would help the server. It would reduce the workload of mods (Pretty much only guests would ever be griefed), give member and trusted a better world, and stop anyone who doesn't want to be griefed having to walk a long, long way to find a place to call home.
