Okay, okay, there are so many guestbooks, but this one is cool and easy to install, I think. This version I wrote from scratch, but it's replacing all my older guestbooks. Just upload it, create the MySQL table and run it. The layout can be done trough a template, or just use the standard templates, described in the readme file. The standard layout can be set trough a CSS file if you know your css a little ;)
