Robert Basic has written up an entire tutorial on how to use an install of the popular PHP blogging engine, WordPress, as a content management system.

You know what's the best part of Wordpress? With some knowledge of PHP and MySql, you can turn it into much more than just a blogging platform. After doing some HTML to WP work for Roger, I thought of one way how could Wordpress be transformed into a CMS. Note the "one way". This is not the only way for doing this, and, most likely, not the best way.

He looks first at working with the static pages, making templates for the site (with code), setting up a few mod_rewrite rules to handle the new URL formats and some code that grabs the parent and child pages of the currently viewed one. He's made a screencast to show how it all works.
