<p>Allows you te set a page to be used as the 404 page. In order for the plugin to work you need to make some modifications to the <code>404.php</code> file in your theme. I set it this way so that the 404 page could be formatted to fit the theme, or can be set more dynamically.</p>

<p>Although this plugin will work with WordPress 2.8, it’s better suited for version 3.x.</p>
