Private Forums By User Info

[Bent Image]

I was wondering if it is possible or if there is a hack to set up private forums by users location or information user gives when they sign up. Example: if a user puts New York as his location he has access to the New York private forums but does not have access to the other private forums, like the Florida private forums etc... Is this something that is possible for vBulletin 2.3.0 to do automaticly or do I have to do this manualy for each member.

Thanks,
Bent
