From their website:

"No Selling!
No Meetings!
No Pressure!

Take a FREE tour. There is NO obligation to join.

This is a well designed, professional site and you can earn a ton of money from their powerful compensation plan.
You earn on three levels.
You earn from your own members and two other levels that come from your powerline. I like this feature. This has the potential to put a lot of money in your pocket.

Note: You must be an upgraded member to earn commissions so don't sit on your thumbs. You have a week to decide before you lose your place and commissions, so be sure to act while the iron is hot!"
