First off, I'd like to say I love the new board. However, the header (starting at "BYOAC Forums") is way to much. I run 1280x960 and it's still way too much. It would be alot better if it could be moved to the bottom of the page, as opposed to the top. Or it really could be removed entirely. The top part lists the forums, which are listed in the treeview above the messages. The other forum links don't need to be displayed for every page I view. Again, I just think it's overkill. I'm suprised nobody else has mentioned this.
Beside that, I think the new board rocks!
