The course room is an open Collaborate session dedicated to the course. You can join this session any time.
Select the session name and Join Course Room to join the session. This generates a unique link to help the session identify you.
Each link is unique to an individual session and a user in that session. This means that the link only works for you in that session. You are not able to use the link to join the session again or share your link with another user. Session links expire after 5 minutes.
If you don't see a course room, your instructor or administrator has turned it off.
