This site lets you click on ads and use your earnings to send your program referrals links out to their member base of more than 1900 people. You can either redeem for banners, paid to click ads on their site or solo emails to members. With no referrals you can redeem quickly and I got some signups off my very first email the first day it went out. If you can use free advertising for any site, check this out, I like the results I'm getting.
