Go HERE for full details, and to join. We have really enjoyed the experience and have never had a problem. I'd highly recommend it. (and no, I am not getting paid a fee to refer you)
There is also a sister-survey site called TeensEyes that Sam is a member of. He just got an email from them about a survey, took it, and checked his point balance. He has $24.50 available in his account. He couldn't hit the Cash Out button quick enough! He's got a check headed his way. Check out TeensEyes HERE.
