Are you guys running MyBB? What system are you guys running? I don't like how this is all cluttered together. I mean- the forum itself is in the center, with the backround taking up a good chunk of the screen. Don't get me wrong, I think that is good, but your making it too much. I'd say make the forum a little bigger.
And what affiliation are you guys running? Ebay? You should use Google ads. I was experimenting with Google ads and Bidvertiser, and Google brings in a lot more income than Bidvertiser. Not saying that you use Bidvertiser.
Edit: I'm a moron. I just noticed you had Google Ads.
Err... this is my first post.
