BNBBOOK is the result of your suggestions, and our own experience in dealing with a busy guest book. It is very simple and easy to configure, but probably offers everything you ever wanted in a guestbook. Dirty word filtering, autoresponder and notification, missing tag and quote mark detector, private message, e-mail address munging, IP address capture, user defined required fields, and more. This script is written in PERL5 for Unix and Windows servers!
