Start a community on Snapzu, validate it to join the referral program, grow your tribe by referring members to it and collect referrals. When the credits system goes live, all credits purchased by your referrals will be split between yourself and Snapzu at a 50/50 rate. It's really that simple. There is a lot of documentation about it in the footer if you would like to know more.
Far more succinct than my response. :)
I think you did a great job explaining it actually!
