• arranging at least some of the profile information associated with the registered student in a queue of the server system, the queue further including different profile information associated with at least one other student;
• removing the arranged profile information associated with the registered student from the queue in response to selection indicia received from a second client system, the selection indicia being associated with a teacher of the course initiating a discussion session, wherein the first and second client systems exchange at least some messages during the discussion session pertaining to the course independently of the server system.
