It would be helpful to put a note in the activity feed of everyone in a particular "tag" list when we send out a note through our College Mail System. This would help us track when we've notified students through other avenues (beside email that can already be posted en masse in the Activity Feed).
The other feature that might be useful here (and I would assume take similar coding) would be to have the ability to create a "To-Do" for an entire Tag list.
