Wordpress CPA Tracking

Hi, Need a CPA tracking system developed for my wordpress blog. The basic concept is this: 1. Have an aweber sign up on BLOG A. Confirmation Landing page is BLOG B. 2. Need to (auto?) create WP user on BLOG B for sign up and track where sign up came from (i.e. record the fact it was BLOG A) 3. BLOG B will contain many CPA offers i.e. [login to view URL] We will need to append a tracking code to the CPA url that ties the sale/purchase/lead to the WP user. The code used will vary by CPA network but all offer the facility (of adding tracking codes and or post back urls to their urls). We will just need to be able to tie a successfuil transaction in the CPA network to the registered user of BLOG B. 4. It would also be useful to cloak every outgoing link i.e. [login to view URL] 5. It would also be useful to have a summary by offer of the ones that generate sales and the ones that don't. (I suggest we would need to have a postback url sent back to BLOG B which detailed the successful transaction, user name, offer url etc.) This would be stage 1 of an ongoing project. Thanks Allen
