Very nice. Love the node icon! Also, very good insertion of the top advert banner in that space under the menu. The only thing I don't like is the shoutbox, it means there is a whole screen of content before you get to the actual forums. I think it would be better in the sidebar, there is room for it there. Lovely colours and slick design though.
Really nice stuff there. Am not a fan of shoutboxes, but if your community is enjoying it, that's great. I don't see the forums being empty, so we can't say it's distracting people from posting
Love what you've done with the site. Nice job
