That's a new idea having a flash file instead of just a picture.. cool!
What jumped out at me right away was how the flash file, background and scroll bar are all just about the same shade of green, which causes everything to kind of blend together - maybe a slightly lighter shade of green in the background might help?
But what also stood out to me was the thin, crisp lines that form the borders for all the table cells (I'm referring to the html code here)... I think it adds a lot to the readability of the forums when I'm looking at a whole page of topics.. makes it easier for the eye to separate things out.
