Bri I've used similar systems that also let you put a priority on a given advertiser's ads. So you'd have 1) evolter ads (or rather, ads submitted via evolters, so if John Dowdell were an evolter and MM ads came via him, they'd be here) 2) registered evolt member ads 3) john q public/company ads 4) ads for evolt.org services "Become an evolter! Write an article! xxxx!

Err. (When I say "it works like..." I mean all the ones I'm familair with as a user or installer work this way.) In my experience it works like a banner ad rotator, so there is no competition. I buy 10,000 impressions. You buy 10,000 impressions. Either your ad or my ad is randomly thrown into the single ad spot until both of our 10,000 impressions are expended. After 10,000 impressions, our ads clear themselves from the rotation. As the ad owner, I can log in and pay for another run, and also edit my ad during a run. Edits go back to the approval queue. I can also see my impressions served to date and my click-thru rate. If the 20,000 or whatever number of impressions are all served up, the system defaults to base ads instead of subscriber ads. Those would likely be evolt's own ads. I think I've used 4 different systems and they've all worked exactly like that. Ergo, I assumed evolt's would be the same. Seems a good, low-admin system to me.
