Seems like you’ve been getting a lot of plugin ideas recently – here’s another one!

This idea is taken from Ning social networks. On there, there is an option for the admin to set a display role for selected site members, for example you can set a role of “Chat Moderator” and assign it to selected users, and then whenever that users avatar is displayed along the bottom of the image is the words – “Chat Moderator”.

So using this method the site can officially assign roles to it’s members and make it clear to all site visitors what role those members have, in any view.
