On the main page the links on the bottom are orange and without emphasis. On the forums pages they are yellow and in bold. Applying the same formatting (I would go with the plain orange) throughout the site would be a good idea. At the moment, disregarding the issue with the buttons, they are the biggest discrepancy throughout your layout.

Also, is the blank space to the right of the google ads (on the main page) intentional? I'm on Opera so it may just be me but the table looks asymmetric without anything there to anchor the right wall. I won't comment on the 'Articles' page as I see you're still working on it. Other than that, it's a pretty good design.
