That's what we call "Super-Mod"... already integrated in the system... set your prefered mods to be super-mods and give them proper permissions.
by logic, a moderator is not a creator or anything, it is a "moderator"... so it does not have any right above managing content... if you want your moderators to do your job, that's fair, so give them the proper level... Super-Mod is the name..
