Marsogram is a tool for a student can to ask for help from a teacher at the tasks where he has issues, and the teacher can pay attention to the student's mistakes or shortcomings.

When the teacher replies to the student, the student will receive a notification about the new message (it can be seen on the following pages: the home page, the course page, Hall of Fame, Entertainment Center).
