The uploader is demanding for TypePad's .xml export file.
It is good that you're moving to wordpress.com. Follow the steps to get your complete Typepad.com blog ported to wordpress.com:
1. Login to TypePad and go to
Weblogs | Manage | Import/Export.
2. At the bottom of the page, (probably) look for the “Export:Your-Blog-Name” link. If you’re using IE, right-click
and Save as; otherwise, you can
right-click and Save as or just open the link in your browser.
3. Save the file to your desktop with a .xml extension.
That’s it for the export. That file
contains all of your posts,categories, comments, etc. Amazing how so much work can be pared down into such a small file, isn’t it?
Now continue the work by uploading that file to your dashboard.
