Looks very good.
One minor suggestion.
Since most people here are returning visitors, would the site look better if you had less announcements at the top, maybe move some of the 'explanation' stuff to the bottom.
Most people that come here want to get right to the meat and potatoes so to speak and do not want to scroll over the same stuff over and over.
just my 2c. (but due to the FED it's now .0002c)
