I know with Xenforo you can also assign a specific person or group to moderate a forum, however, what was nice about those aforementioned boards is that it would displayed on the main index at the bottom of said forum something like "Forum Moderated by: Person1". People would then apply for a forum moderator position and it would encourage them to post information, stickies, etc pertaining to the forum they were "in charge of" upon being accepted for the position.
I was hoping someone could develop an add-on that would display this information on the index for everyone to see. If it already exists, even better. (Just point me to it )
