I am selling a simple comments system (full AJAX). I have designed it in a way that I hope is easy for anyone to integrate into their web page with little knowledge of PHP/MySQL. Here is a demo, feel free to use it: http://easycomments.x10.mx/ Cost is currently $5. Accept payments via PayPal. Any updates made after you purchase will be given to you at no charge. These updates, however, would not be required to be installed. PM me or post a reply if you are interested.
