I know, no one likes to have there browser cluttered with ads all over the place, but this is a valid question. I have ran many forums/websites through my years and have somewhat figured out the best way to do this. In my experience, I have paid the bills with more membership/ad reduction fees than actual advertisement commission. With that said. I would like to know how easy it would be to implement an ad system to Xenforo and turn them off with an account upgrade. I'm not talking about ads galore, just ads at the top bottom and after the first post.
