A question about the system

[محروم.كوم]

I have read about bulletin board system, and I'm interested. I have a couple of questions.

I currently run 5 sites under Content Teller CMS. Different sites run under the same user database, and they do have related but different content. I'm currently using the built in forum software, but would like something a little more robust.

I want to keep the shared user database, and some shared forums ie a social fora or lounge, etc, but would like custom content for each plus the ability for the user to get to the other content. Basically I want to have the integrated use that I have with Content Teller. ie a site id for the different sites and unified management of the different domains in one admin panel.

does this software have that, or do I need to find another solution? __DEFINE_LIKE_SHARE__
