Dean Allen, after a year and a half of anticipation from the blogging community, is just about ready to release the first version of TextPattern. He's currently looking for testers.
Textpattern is a server-based system designed to simplify publishing on the web. It is intended to be very easy to use. Upon installation, only a web browser and a connection to the internet are required to publish and maintain a web site. Little technical knowledge is needed; those who wish to write on the web, but who are perhaps daunted by the learning demanded by markup languages such as HTML and XML and the presentation language CSS, may find Textpattern to be what they're looking for.
It's written in PHP, has a MySQL backend, and, from what little I can gather without looking at the code, seems to be well written.
Good luck, Dean. I'd be happy to help you test.
