Have you heard of Moola? It's a great new service in beta right now that gives you a chance to make money. Okay, this is how it works. Moola is a games server that uses advertisements, shown at the beginning of each game, to generate revenue. Then they give you a penny to play games with. You bet that penny, and if you win, it doubles. You move on to the next round, betting 2 pennies, and if you win, it doubles. If you lose, you lose everything, but you can cash out at anytime, and Moola always gives you another penny to start over with. You can also receive bonuses from searches through Moola, and taking offers in their booster zone. The booster zone contains some paid offers, but there are also trials and free offers as well.
Here's the catch. You can't sign up for an account at Moola, yet. Their beta testing is running along the lines of how Gmail worked, and how Joost is working now. If you want to join, you have to find yourself an invite. You can post on the invite forum and wait for someone to send you one, which is honestly the quickest way to get one, or you can add your name to their list to receive future invites.
I also have a few invites left, so if you're interested in one, leave your contact info in a comment, and I'll gladly send you one if I have any left. As of right now I only have 3, so it's first come first serve! If you don't want spammers grabbing your email addy, just enter it as yourname AT youremail DOT com to prevent this!
