Note that you could also import your comments. Just make sure your comments exist within each "Item" element in the following format:
<comment>
<author>Commenter name</author>
<email>Commenter email</email>
<url>Commenter website</url>
<date>Comment date</date>
<content>Comment text</content>
</comment>
Remember that you may have multiple occurances of comment element within each "Item" element (because a post can have many associated comments). Duplicate comments would automatically be ignored.').'
