It's great that the affiliate plugin can track from any part of your entire site and that you can select your user blog instead of the main URL.
The only problem is that those two pages might not be your actual sales page or a page that converts members.
Could there be an added functionality in the settings to add multiple pages and assign different banners to different pages across a site? And also list the different text links with titles?
I find that my affiliates don't always know which page to promote in their campaigns.
