Need both Public and Private Forum...

Eliteoomph

I am trying to create a forum that will have both public and private forums... Is this possible? I want there to be a general forum and then private forums that either I assign members to or they can invite each other... I see this is an option separately but can't figure out how to do it on one site? Is this possible or do I need to create sub domains and install separate forums?

I use categories set up with custom permissions.. simple to use and manage
