I like it, except for the flash at the top. It's hideous, to be honest. In general, I detest flash headers. it's ok for applications (such as video and mp3 embedded) . Where is the link to return to the main page? It's not where expected - the header. More custom icons for the forum which fit in with the rest/site theme and also a better colour scheme for the forum. I mean the background ones (for the different fields where there is forum name, number of threads, posts, etc). They are not bright and lively like the other colours. That's all I can think of for now. After you've made some changes, ask for another review.
