Millennium, the fantasy/adventure, has three ad areas (skyscraper to the top right on every page, mildly experimental button trio near the middle front page, one half-banner at the bottom front page)
Lovefeast, the BL/action, has one skyscraper on the front page
As I just got Project Wonderful adspace, they are nearly free! Their bids are at $0 or $0.01 right now. Go! Go! Check it out! Promote yourself!
A question - do you think it'd be a good idea to place some of these ads (notably, the skyscrapers) on my mirror sites? I don't want to get too obnoxious with them.
