Hi, first post here. Nice forum.
Anyway, Clickbank has recently introduced an improved tracking system that can track sales in instances where cookies can't be set. For example, user's with paranoid browser settings that block 3rd party cookies or users that have Spybot installed.
Clickbank started the new system on the first of May, and my sales have been better since the change. I'd encourage newbies to give Clickbank another try.
