Advertising Know-How

Advertising Know How is a new subscriber exchange program. Think along the lines of subscriber drive, optin-storm, that kind of site - except this one is (supposed) to be only used on the subscriber "thank you" page and it has many top marketers involved. Looks good, and should increase your sign-up rates - since it's 1:3 ratio (you show 1 and get 3 impressions).
