I'm coming up with the basic ideas before I start working on this. 1. It would be nice to have a button on each post labeled "feedback" in the classifieds forums, and not on the rest. Everyone that post in the thread can only leave feedback for the thread starter and the the thread starter can leave feedback for anyone in the thread. . 2. Ad a link to each users feedback under there username. When you click on this link, it would popup a new little window or use ajax and highslide to display #3. . 3. Since it's based of the thread, this would prevent fake feedback. Since you must have a thread that would link back to the deal you made. All feedback listed would include a link to the thread. .
