Let me see if I understand something here. I've noticed now that I'm at a different computer and a different IP address that the radio buttons are visible where they were not before on the showproduct.php page. At least on the showproduct.php page. The reviews.php still show the radio buttons. I'm assuming that the IP of a user is tracked if they post a review. Is the reason behind this to prevent a single user from rating multiple products? I'm still not sure I understand the logic if this is intentional.
