vb 4.04 is supposed to have a facebook bridge in it, whereby threads go to a facebook site along with your forum. I think vbulletin is staying on top of this issue, and, unfortunately, (I'm not a facebook fan by any means...) this whole interaction is here to stay.

I think that when you connect with facebook connect, and you're a new user to the forum, vb creates that user in your database. If you're a current user, and you connect with facebook, it will either log you in as that facebook user, or, you can associate your facebook account with a current forum account.

And then, to complicate matters, in the typical "take over the world" facebook fashion, when you log in with an account that exists on your forum, facebook creates yet another user (your forum user).

I'm not quite sure I understand it all yet. But, unfortunately, for those of us with websites, I think this is going to be a necessary evil.
