I'd love to see the font sizes bumped up a little (ex. similar to V7n). I find them a little small and I think you might get more readers and responses. Of course I can always do this in my browser, but just a a suggestion that might help with the participation. Probably a slightly darker by still light grey background (the one on the extreme left and right and around the forum may also give a little better 3D effect and help the content "pop" a little more.
