Shared Usertables with Multiple Licenses?

[Rich]

Hello,

I currently have 4 active licenses. 2 are owned, and 2 are leased. I will be moving my sites to a new server shortly, and I want to integrate them.

Each site has its own identity, and each site has its own purpose. They will all be on the same server but each will be in a subdomain with their own DNS.

I want all of the sites to use the same user tables. When a member joins one site, they have joined all of them and they are displayed in all of the memberlists.

I don't want them sharing anything else though. lol I want their posts and threads to be independant.

Is this possible? Would this work? If it is possible, could someone let me know how and what I would need to do in order to pull this off.

My biggest thing is that when they switch between the sites, they are logged in already if they are 'remembered". Thanks for the assistance.

Hello,

This is just a bump. I would like some input.
