<p>Howdy! This importer allows you to extract posts from any RSS 2.0 file into your blog. This is useful if you want to import your posts from a system that is not handled by a custom import tool. To get started you must edit the following line in this file (<code>import-rss.php</code>) </p>
<p><code>define('RSSFILE', '');</code></p>
<p>You want to define where the RSS file we'll be working with is, for example: </p>
<p><code>define('RSSFILE', 'rss.xml');</code></p>
<p>You have to do this manually for security reasons. When you're done reload this page and we'll take you to the next step.</p>
