This how-to video steps through how to create Ultra session for your class. It briefly describes why you might want to "create sessions" for each class rather than using the "Course Room" and suggests you lock the "Course Room" during class time if you "create sessions" for each class. 1) go to Collaborate Ultra in your course 2) click "create session" 3) type in title of class (date, topic?) 4) click if you want a guest link 5) select the date/time for your course 6) decide how early the class session will be available to students (default is 15 min) 7) click "save"   8) lock the "Course Room" when your session is live to ensure students don't go to the wrong room
