Looks nice. I would say that the X button to close each section should be placed consistently. In the news section it is in the bottom right, the bio section it is in the bottom centre. Actually the bio section is the only one where it's out of place, but I'd have it in the same place the rest of them are.
If it was me I wouldn't have the message board open a new window, I mean it's still part of your site. Have it open up in the same window, and have the top banner a link back to the main site, instead of back to the main page of the message board.
But yeah nice looking site, clean and easy to use, but like everyone else has said could also do with some more content.
