I am currently in the process of trying to get my CL game setup. I was wondering, do most of you, or any of you for that matter, use prosper202 when you have links in your ads to track them?

Also, they way I am doing it is first collecting email addresses and then emailing the offer(s)....with a link in the email. When the user clicks on this link and is taken to the landing page, what do the affiliate networks se as the referrer? Do I need to somehow mask this even though it's in an email? If so, how?

Well if the user is clicking ur link from the email then the referrer will be shown as the email client theyre using.
