Free Ajax Guestbook Application: JibberBook

JibberBook is an open source Ajaxed guestbook application built with PHP5.

It stores the data in a XML file (optional MySQL support) and provides an easy to use interface.

For security, JibberBook uses:

• HTML Purifier (see WRD post) for filtering inputs against XSS attacks.
• Akismet for spam protection so users won’t need to enter captcha information.

This PHP guestbook application uses Mootools and it is unobtrusive (it will work even if the JavaScript is disabled).
