Hello.  Sorry if the subject's incoherent.  I'm wondering how to go about getting PunBB to use the login from a different php app to avoid users having to register and login twice.  The app in question is eFiction, and I'd like to get PunBB to use eFiction users/db if possible.  Hint or starting points are appreciated, and hopefully I can manage on what basic PHP I do know.  Thank you.
