Here's what you do: You go to the website; enroll (providing an e-mail address, zip code, and say that you are at least 18 and a U.S. resident), and you will be awarded 3000 "Greenpoints" just for enrolling. After you get your Greenpoints, you can redeem them for prizes. For 2700 Greenpoints, you can get a certificate worth 500 frequent flyer miles, either from American or Delta.

I just enrolled, so I can't say that all this works, but that's what's supposed to happen!
