Setup Unlimited Referral
Here you can offer your users referral bonuses on multiple referral
You can set the number of credits a referrant gets when a new user
signs up on each level.
You can also set how many credits a referrant gets per site viewed
by their referral on each level.
Level 1: I Refer Bob.
Level 2: Bob Refers Mary
Level 3: Mary Refers George
Level 4: George Refers Gary
In above example Gary is my level 4 referrant, when Gary signs up
I will get whatever signup bonus is setup for Level 4 and how ever
many credits setup under level 4 under "Per Site Viewed"
every time he views a site.
