302566 Affiliatesystem for Moodle

I have a language online school. The platform for my courses is Moodle 1.5.3 To drive more business to my page I need an affiliate system. My choice is "Post Affiliate Pro" - [login to view URL] Although I'm a Webdeveloper myself I have no time whatsoever to do the changes in Moodle myself - I rather focus on the producing courses. Actually this shouldn't be a big problem for somebody who worked already with affiliate systems and/or PayPal. I maybe mistaken but it seems that one particular page in Moodle needs modification. Here some more helpful information: - Database: MySql - PHP version: 5.1 - Server: Unix - Future Entry Page: [login to view URL] - Payment method: only PayPal - I will stick with PayPal - PayPal - Moodle: it seems to be a IPN script - Provision method: Affiliate recieves a fixed percentage of every sold course (like 25 %) - no other methods like "Pay-Per-Click" or so will be integrated - the "Fine Tuning" of the affiliate system I can do myself once it's integrated in Moodle - the security aspect is important! - you should know how to make PayPal IPN safe For more info / questions feel free to ask.
