PHP Guestbook

This is a PHP script that takes information from a HTML form and writes it to a guestbook include file, which can be included into any other PHP file. It has the following features:

• Notifies you when you have a new entry, and can also send an autoresponse to the visitor.
• Everything is totally customizable - the colours, HTML, autoresponse, thank you messages, etc.
• Can be viewable in all one file, or have separate signing and viewing pages.
• Strips HTML from entries if you want, and converts emoticons to smiley images.
• Checks that the visitor's email address is valid.
• Sends you the visitor's IP address and browser information in the notification email.
• Censors cuss words.
