A communication powerhouse Instructors have the ability to interact with active students in a "live/realtime" or "offline/delayed" manner and for students in same course can form student peer working groups. Questions from students come complete with a detailed context of the student's exact place in the course at the time of the question, since questions often require context to be answered decisively.

The communications capabilities don't stop there... you can send important notices to a secure internal mailbox, you can pop up a message on the user screen using "push notice" which does not even require the program to be running.  You can even send an audio or video message as a "lesson".
