An instructor who has been re-assigned to a new course should log in to BeachBoard and verify that the course(s) listed under "My Courses > Courses You are Teaching" are indeed the courses that h/she is assigned to teach. The newly-assigned instructor then has the option to execute two separate actions:
Guests are able to view areas of the course, but cannot participate unless the instructor makes a tool or content area available. In addition, users with the role of Guest have no access to the Control Panel. Areas within the course have to be made available to Guests via the Control Panel. Course areas and materials that instructors have added to their courses are automatically available to Students, but need to be made available to Guests. Steps on how to enroll a guest are available in the BeachBoard Instructor Help pages.
