Separate Forums, Shared Members

[shell]

Hi,

I'm

1) thinking of setting up two different vB forums on two different sites,
and
2) I'd like to be able to have the members of the two different forums be able to mutually access one particular sub-forum,
so that
3) the members of these two different forums can interact with each other.
4) Another factor is that at least one of these groups will be using paid subscription,
with
5) access rights revoked on end of subscription.

Any suggestions on the best way to get users on two separate secured bulletin boards able to interact?

Thanks!

There is no feature in the software to share the user database between two separate installations of vBulletin.

One option is to simply create different categories within a single installation of vBulletin.
