A free guestbook for your site. Very simple to use and easy to set up. It has several layers of spam and robot protection (well, as much as possible) and can be configued to send you an email when someone leaves a comment. A better optional verification system is included which isn't as annoying as the captcha system. The script is very configurable and can be easily adapted to your website and best of all -- IT'S FREE!! Uses a flat file database, no mysql needed.
