This plugin just doesn't work well. Many of the problems are already listed in the forum, but here are a few of them:
* When importing, the status (MAX_NUMBER) of number of posts/comments is reported always 0.
* The maximum number of posts it will import by default is 50. (Seriously, if I had only 50 posts on a blog, why would I import it?)
* Comments never import.
* tags/labels never import
* all posts imported start with a "greater than" symbol both in the text and in the title.
* There doesn't appear to be any support for this plugin, judging by the number of people who have commented over the past year in the forum.
