Prattle is a message board system implementing a clean linear model.

You can see Prattle in action at the Prattle test site.

In its organizational scheme, it is similar to Web Crossing, Citadel, the Well, et cetera.

It is designed to support conversation, not questions and answers.

Prattle requires PHP4 and MySQL. It has been tested only on Linux with Apache.

You can participate in Prattle development at the Prattle project page here on SourceForge.

You can download the code here.
