My Guestbook is an easy to use and install
guestbook script. It is fully customizeable with a
combination of CSS and HTML templates. Visitors
can leave you a note along with their name, email
address, and location. This works well for
personal Web sites, and is customizable enough for
professional sites. It also includes comprehensive
spam-fighting features. In the Administration
Panel, you can ban IP addresses and keywords if
your guestbook is being used by spammers. The
admin is emailed when someone signs the book.
