@full-measure not really. Your main argument against an affiliate program is that people can cheat and refer themselves. I guess I don't see the fact that some people may do that as a reason against the program. I was referred here by my brother, and if he had an affiliate link available, I would have gladly used that when I signed up. I recruited several of my friends, and I'm sure they would have been happy to signup using my referral link as well.
