vBulletin to YaBBSE conversion?

[Lauren]

I am helping with a site that is converting from vB to YaBBSE.  Is there any way to use the mySQL user table from vB and somehow convert it (typing in 230+ profiles isn't my idea of a wonderful time)?  Here's the table structure.  Thank you very much for any help that you can provide! Just email me if you have any questions.
