This plugin will import comments from a Disqus export file.
Due to a limitation with the current version of the Disqus Comments plugin the import does not retain nested commenting. Once this support is available in the XML, we will provide support.

This plugin will remove any of the default WordPress comments features from your site, and replace this with Disqus.

Reasons to use this plugin:
<ul>
<li>Simplify your WordPress dashboard by removing the “Comments” admin menu.</li>
<li>Easy setup: simply add the Disqus shortname in the settings and you’re all set.</li>
<li>Comments are NOT imported to WordPress – save server resources and database size.</li>

<li>It has a silly name.</li>
</ul>
