For all of those wondering how the IPT was going to track their referrals - check out their new affiliate program. It's really, really well-done! After the user fills out a small form asking for name, address, etc - the screen is re-directed to a cut/paste screen where you can plop banner code or links to embed in websites or e-mails. I guess the code already has your "affiliate ID," so they know who referred the lead, and who to pay automatically.
