Ok, so im almost done setting up my server ( I saved pex for last :3) and I need the permission for /gamemode 1. Thats all for now xD
If you're using Essentials the permission should be essentials.gamemode which will allow the player to switch between survival, creative, adventure, and spectator. If you're using the built in /gamemode command, then the permission will be bukkit.command.gamemode I think.
