Sign the contract (Important)
This is an expanded idea of y4n3k's original idea.
Once you sign-up, you automatically sign a contract for one month. Then once that month has expired, I will talk with the member about whether he has my approval and their agreement to stay. After that, they would sign for another 2 months. The same would happen after the 2 months is up, then they'd sign for 3 months, 5 months, etc.
What do you guys think about it?
