When I import from another WordPress site posts, categories and tags are imported, but users are not imported. Posts are all assigned to the same admin user.
I've modified the XML to include only a single post and to ensure that none of the users has duplicate email or username with the existing user. I've also ensured that no usernames have uppercase or non-alpha characters.
Here's a sample of the XML I'm importing: http://plccorg.wordpress.com/sample-wordpress-export-xml-for-import/
Any ideas what else could be going wrong?
The blog I need help with is plccorg.wordpress.com.
