I've been using this site for a couple of days and I like it a lot. They give you $4 free just to start you out. You use that to purchase an ad package so that you can promote your links. An added bonus is that for every day you surf 10 sites as a free member you get a % of that $4 back into your account. It's like $0.16 a day but it's free money. I repeat FREE MONEY! So they pay you to promote your links. You can make money even if you don't post a link, you just purchase the ad package with the $4 starter money and surf the 10 sites a day! Easy stuff! Get Started
Hope this helps you!
