I think it could be nice for there to be a rank, where you can get access to worldedit within a worldguard with a flag ticked for it. The rank would not be a primary rank just something that allows you to have the permission, not give you an ingame rank in the tab or anything.

The way I've thought it could work is if a player proves there a good builder etc and would think worldedit could help them build they could apply for this rank etc, and upon being confirmed there then allowed to modreq for ability to use it within a worldguard, which a mod could add as a flag.

It would only be allowed in areas where it would be used to just make nice builds etc, not to benefit the user of it, for example in the creative world, where they could use it to build amazing looking things that would otherwise take months.

Mentioned it to jack and he said it could possibly be worth suggesting so heres to that.
