Thanks for the honesty Paul. I was under that impression myself but, being new to this, I didn't want to come out and say something without having first hand knowledge. I've been in IT for over 30 years and running something like Clickbank without a method of contacting affiliates who sign up seems totally idiotic to me. Now I understand.

Looks like I'm going to have to dig deeper into this rabbit hole called IM and see what I can come up with for running my own affiliate network and paying affiliates myself.
