There's a referral contest at www.profitgeek.com, and whoever has the most referrals by December 25 I think it is will win $250 USD. There is also a forum contest where you can win prizes just for having a post average of 3/day (giving away multiple prizes every day, some users have won 5 times), and there's a jackpot on Christmas also. There's more information in the contest section of the forums. 100% ad revenue is shared in the forums. A point worth mentioning .
