Is it possible to make referrals for subscription system?
 

K so, to use our subscription system, you first of all have to be registered.

I was wondering if it's possible to somehow implement a referral system for our subscription payments system thats implemented into vbulletin.

So that, a person would refer someone else to subscribe monthly, and the person who referred, gets a percent discount deal or gets his subscription extended based on the following criteria:

a. Referrer would get % of how much other person subscribed for added to his subscription only one time.

b. Referrer would get a fixed amount of money added to his subscription only one time.

c. Referrer would get money added to his subscription based on how much the other guy subscribed monthly for.

d. Referrer would get a % discount for one cycle only.
