Honestly, I setup JROX software with aMember and it works great. I took a look at Post Affiliate Pro, but I still like JROX setup better. My 2 cents Now, for your question. I'm sure others will have their ideas, but what about this: You need to add the image to the thank you page, right? Well, add it -after- the 3 days is up. Set a cookie that is say 'trial'. After the 3 days, when they log back in, change that cookie to 'registered', then show the affiliate image. You might need to save the original data to a database and recall it later. Does this make sense?
