The functionality in this plugin was incorporated into the built in export feature in WordPress 3.0
Working with a single large export file can be difficult. Use this plugin to create multiple export files that contain sections of your blog. This plugin has been tested on WP & WPMU versions 2.7 – 2.8.4. The plugin may work on earlier versions of WP/WPMU.
All restriction options provided in the plugin are optional. If no restrictions are selected, this plugin generates the same export file as the export feature built into WP & WPMU.

<ul>
<li>Date Range – Start & end month/year</li>
