Where can I find out more about the session variable that is assigned to each person? I want to link an active person to a second MySQL database.

PHP Sessions manual

It's now 5 years later and I'm still thinking about a solution to this situation.

I'd like to have my users log in to our Membership MySQL database - and then use THAT credential to jump over to our THREADS MySQL FORUM.

Is this done by "snyncing up" the two session variables? Will Ver 7.6 offer any improvements to assist in this?
