Mine is a small very social oriented board, with a lot of protected content. Not live yet so some places empty of content.
The design is not standard and not at all the fashionable grey and black.
Has a nice feature of category design inherited through category content with a forum level logo and colours, containers.
I am implementing a "joinable forums" addon which acts like social groups. Each category uses the colour/ logo design theme to strengthen group ID.
Probably nothing like what you want but it does add to the range.
You're welcome to look. See my signature.
Not done but a fairly big system (well will be when done and a lot is behind the scenes). http://savagerebirth.com. Maybe you should tell them IGN is converting to XenForo, might help them make their decision.
