Command Centre: Org and Team setup
Two admin-side tabs of the Command Centre's Manage rail set up who runs a course before the first session: Org is the institutional hierarchy, Team is who else can teach or moderate.
Open Command Centre → Org. This is the institutional hierarchy - school, department, course, class - the structure everything else in the Command Centre hangs off.
Team is who else can teach or moderate this class - roles and sharing, for when a course has more than one instructor.
See "Command Centre: Badges and Class settings" for the other half of Manage, and "The Command Centre" for the day-to-day teaching workflow once setup is done.
