Is there a hack for this?
 

Our Forum runs on 3.6.4 and has the 7 default usergroups plus 18 custom ones. I want to find out how I can grant to one custom usergroup (which normally does not have moderating privileges) the ability to fully edit (i.e. at any time) all threads within a specific subforum only. I do not want to assign this usergroup's members as moderators to this subforum. I do not want them to have these additional privileges at any other area beyond this specific subforum, either. I was told by vbulletin.com this can't be done within vB. So, I'd like to know if there's a hack that can provide subforum-specific customization for usergroups.
