Question about Convert WP authors functionality
 

What is this supposed to do? Is this in place so that you can create WP authors and then attribute all of one's posts make through VB to a WP author which is supported throughout the WP blogging system?

I'm confused about this. Can you help me out Jeff?

You would only do this once, if you were converting an existing WP install with lots of posts to a bridged one. Generally do not need to use it unless authors are not aligned correctly.
