I was looking for a tagboard-guestbook type thing for a site and couldn't find one quite like I wanted, so I wrote my own. It's been a learning tool for me as I explore php development, but some people have found it useful, so I've packaged it up for release ( a good exercise in itself ).

Features:

* Coolio text character counter lets the poster know how much more they can enter (input field limited to 250 characters)
* Administration panel to edit/delete posts
* Installer script creates the required mysql table
* All functionality is contained in a single file
* Displays country flag of poster (based on an IP lookup at hostip.info). Flag display can now be turned on or off easily
* Mouse over a comment to see the date/time/ip of the post.
* Easily modifiable CSS styles to suit your site layout
* Modifiable bad words filter
* Flexible implementation - it can run in an iframe, a new window, or as it's own page
* Easy to create multiple instances. You could have topic-specific comment areas throughout your site (explained in the documentation)
