Tips
To the end of the url that you want the affiliate to link to, you would add ?affID=affiliatesID.
For example, if you wanted to direct an affiliates users to your sales page, the url would be:
http://www.yoursitename.com/public/main.cfm?affID=affiliateID
Its important to realize that this link must be at the end of a MemberGate generated page. In other words, not a html page that you uploaded seperately to your server.
