Sure, there are a ton of guestbook scripts out there, but we couldn't find one as well thought out and feature rich as the guestbook program we wanted. Hence: VisitorBook Pro. We packed in a ton of great features (you name it, we got it) and laid a slick, clean interface on top of it. And VisitorBook Pro is customizable; you can modify and tweak every parameter of your guestbooks to make them look and function exactly how you want them to.
