I'd like to come up with another suggestion.
Problem:
-The server has obviously some moderators or operators. I'd like the mods to be able to modify worlds, but not to load/create them.
Reasoning:
-Sometimes the server get flooded by worlds. Yes, I know it's ''just to tell them to not,'' but it would be a lot easier just to disable it, right?

Suggestion:
-If we could make two separate permissions, ManageWorlds, and AddAndRemoveWorlds, for instance.
Thanks for reading,
