Forum Role permissions, How do I set up role permissions for containers and forums?

Hi,
I'd like to create several forum containers, each containing several forums. Is it possible to assign or restrict some of containers/forums to different roles. For instance

(These containers and forums would be open to the general public(Annonymous users)

1. Public Announcements (Container)

1a.) Announcement Board - (Forum - open to public)
1b.) Employment - (Forum - open to public)

2. General Category (Container)

2a.) General Discussion - (Forum - open to public)
2b.) How to's - (Forum - open to public)
2c.) Humor Board - (Forum - open to public)

3. Upholstery - Public (Container)

3a.) Upholstery Questions
3b.) Training Centers

(These containers and forums would be open to the general members)

4. Upholstery (Container)

4a.) Upholstery techniques (Forum - open to general members)
4b.) Management (Forum - open to general members)

(These containers and forums would be open to the Professional Members)

5. Pro Upholsterers Members

- Professional members (Container)
5a.) Chat Room (Open only to Professional members)
5b.) Preferred Suppliers(Open only to Professional members)
5c.) Special Topics(Open only to Professional members)

How would I set up roles and/or permissions so that Anonymous roles could access containers/forums 1-3. General members/roles, could access containers/forums 1-4, and Professional Members/roles could access containers/forums 1-5.

I have looked and couldn't find any way to assign roles and permissions to forums. Could someone tell me how to do this?

Thanks
Stephen
