Ever seen a theme that you like and want to test it all filled out with content? That can take some time to create. This is why WordPress.org offers a sample content file for you to use when trying on and testing themes. If you’re using WordPress 3.0, you’ll need to install the WordPress Importer plugin first. Save the sample content xml file and then import it into your site. You’ll be able to test any theme and see how it interacts with the content. This is a time-saving option for beta testers, theme developers, or regular WordPress users shopping for a good theme.
