I have several online courses.  I'd like to be able to create a forum with subforums or separate forums that only the members of a course can see.  My goal is to have people who take a course only be able to use that course forum to communicate with members of that course.  I dont want people who are not in a course to see that course's forum. 

Example:  there are 5 forums or subforums - each one assigned to a certain group of subscribers (people in Course A for example)  The people in the Course A forum can view, create topics, reply, etc. within the Course A forum.  They cannot access the Course B forum.  

Is there a way to do that with wpforo?  

Thanks,

Evelyn
