It's fine, the website is great on its colours. I like how the website and forum match together, thats amazing. You seem to have alot of content.
Everythings fine, your ads are in a great place. Only thing I would say is, you adds are under each other. You should make them on the same row, so there both oposite each other. Other than that it's fine.
Also, you site seems to lagg a little for me. Im under Intel(R) Celeron(R) 2.4GHz, 256MB RAM. That may not be too good specs. but there will be users with the same specs. as me or lower. But most users will usualy have higher so thats not too bad.
The lagg is the only problem in my opinion, other than that it's great. Good job.
