Give a usergroup the ability to edit other posts without making them moderators.
I'd like to be able to give a usergroup the ability to edit each other's posts without making them Moderators or modding them into a forum. This is for a game (I explain because I know it sounds nutty). And if this is something that would be relatively easy to do but why bother because nobody else is going to want it - I'd appreciate knowing what kind of price would make it worth your time.
