I would like to use the affiliate function as a "member appreciation" feature and wanted to know if the following is possible. I would like to set up to have any member that refers users get, let's say, 20% commission on the referred users to apply to the the affiliate uses subscriptions up to the subscription amount for that month. This would be on a recurring basis. So for example (assume all subscriptions are $40) if the affiliate user has 5 referrals (5x$40=$200 at 20% = $40 commission) so that affiliate user would be billed $0 for that month. Additional referrals would not credit since the affiliate users monthly billing is $40. So basically as a member appreciation program you could earn up to free use of the subscription, but not over.
