We'll create fresh WordPress site with Disqus Comments Importer installed. You have 20 minutes to test the plugin after that site we'll be deleted.
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.
Please provide feedback and bug reports in the Forums
