XML-Guestbook is a tiny, light but nice & full-featured guestbook. It has a pager for large number of messages, it supports smiley images & hyperlinks within messages and uses CSS styles. When posting, malicious characters are automatically removed from messages and data can be e-mailed to administrator. It can be used more than once in a website either as a standalone page or included into another page. Messages are stored in a text file in XML format including IP, time, country & other info. Very easy installation & configuration.
