Content Management & Delivery Systems
 

Does anyone know of a good content management and delivery system?

We have 10 websites and when someone joins through 1 of them, they get all of the content that is for that particular site, but we also want to allow them to see parts of the other members areas as well. We need a system that would keep all of our content in an SQL database and allow us to define who gets to see what.

I know there are a bunch of systems that do stuff similar to this, but does anyone know of one like what I am looking for.


Thanks!
