Can you import users from an existing DB into vBulletin?

[Mr Viper]

I posted this in the regular vBulletin board, and they redirected me here.

I've been looking all around for BB software that can do this, but I've had zero luck so far. I have an existing MySQL database, with usernames, passwords, AIM info, etc. If I were to install vBulletin, is there something in the code where I can have it access my database and load that info instead of making users register twice?

You can create your own import modules for vBulletin's Import System, called ImpEx (http://www.vbulletin.com/docs/html/impex).

Or are you talking about a bridge?
