If you are new here, I hope the infomation beblow will help you to understand this great system works:
It takes me half hour to understand the rules in this program. It is much different from others:
1) The first time upgrade must be $10. More than $10 is not allowed.
2) Only one active upgrade is allowed.
3) When your first upgrade goes expires, your max upgrade will be $20
4) when your second upgrade goes expires, your max upgrades will be $30....
5) There's a 2% upgrade fee and 2% cashout fee.
With these rules, I think it will run for a long long time.
The info above, I wrote it on 2009-12-11 and today is 2010-03-11. So, Time tell me: I am right
--- "With these rules, I think it will run
for a long long time.."
I am so happy I was in and I think it is still not late to join and upgrade today.
