I'll send you the stats we currently have but overall it is about 15,000 impressions a day, and generally 50-100 clicks depending on what ad is up. This is for the large and medium sized banners, I believe the large banner gets more than the half size right now.
I've never advertised the advertising haha, it was kind of just a thought I never got around to doing.... I think CPM advertising might actually get you more clicks, not sure though. I wanted to put a banner at the top of x10 next to the logo but everytime we try it messes up the forum so I might have to pay to have that put in.
