The roles for message boards is not labeling, but more giving permissions for various things like deleting posts, editing inappropriate postings, and overall moderation. Especially for a public join group, it's dangerous to openly give leader permissions to everyone that joins. I understand that we're all leaders together, but any user with leader permissions can cause stress by doing things like deleting other users, deleting posts for no reason, or even take over the group by changing permissions of other users... This is just a heads up, but it's up to you. I'm not trying to stir up fear or paranoia. I only hope the best for this group even though I just joined it.
