I am looking for a comment system that will use AJAX, PHP and MySQL. I would like the comments to be stored in a MySQL database. I need a system that can be placed on any page of my site and preferabbly runs on an ID system so if needed I could have two different comments on one page. It will also need some sort of captcha system as to not be prone to spam.
The user will only need to enter in their username and a comment.
