A Free PHP/AJAX User Comments System for your website

At some point, most of my websites have required a User Comments System, and yet I can never find one that does everything I wanted it to do, so I decided to create my own.

I wanted to build something with all of the following features:

• Search Engine Friendly
  Comments should get indexed as part of your page’s content, building a richer, fuller site, rather than being included client-side with JavaScript like with other systems, such as DISQ’US.
• Easily Inegrated
  Comments System should feature simple inegration into any webpage with just a couple of lines of code.
• Spam Resistant
  Comment System should feature a CAPTCHA-code verification and Akismet Spam filter to minimize the posting of spam.
• AJAX-enhanced
  Post new comments asynchronously to the server to provide a smoother user experience with less page reloads.
