Several of our instructors are departments leads and are automatically enrolled as TAs in each course in their department. This leads to their receiving an enormous number of notifications and To-Do List items for these classes, in addition to the ones for the courses they actually teach. We've shown them how to turn off the notifications for these extra classes, but we can't seem to do anything about the To-Do List items. Is there a setting or anything else we can do about turning these off for TAs?
