                 <p>When an user is designated as an instructor for a simulation, he or she will see that running simulation in their list of 'My Sims' and will be able to access the student dashboard for that simulation.</p>
                 <p>Note: making someone an 'Instructor' in a simulation does not automatically add them as a player in the simulation. Someone can act as an instructor (assigning players, checking on players, etc.) and never actually enter into the game world. </p>
