Ok have a bit of free time
I really like your design, I think I have seen it on other sites but yours looks different, did you do anything to customize it?
Everything seems very well integrated throughout the design, you have a comma after Search in the top navigation though.
All your resource links just go the your index, you would probably just be better off removing those until you have the sections complete.
Adsense looks to be integrated well on the homepage - You don't have ads on any other pages, maybe you could integrate it in the forumdisplay page.
You seem to be growing very quick, any hits or tips that you can share there
Another suggestion, add webmasterforums to your recommended links page
Looks good, keep up the good work.
