I finally got a green on free360xbox.com!!
1 green and 4 yellows (that I hope turn green). I need to figure out how to get more referrals. Seems like people ignored my post in the trading section, and I can and am willing sign up for almost any of the free sites.
You may want to raise your price (I have had to pay $30 for xbox360s.freepay.com refs before) to get more refs. It also doesn't hurt to PM users who advertise that they are open to trades. Good luck.
