I'm looking for an affiliate mod that pay referring user only when his referred users signup for a paying usergroup, NOT when they signup for the forum.
I have checked out the following mods but do not meet my need:
1. Referral Plus 1.4.0 - pay users based on signing up the forum
2. Cash mod - pay users based on their post contribution to the forum
3. Karma mod - pay users based on their post contribution to the forum
4. Kinix Affiliate - dead
Does anyone has any knowledge of any mod that meet my need?
