The head of our Athletics program wanted to Message a team when their coach was out sick, but she is only able to Message the coaches. I think this doesn't make sense! She would have to message the coach to message his team. Or she'd have to be made a coach of every team. Or she can impersonate the coach and message them. None of these options are great. Likewise, the English Dept. head should be able to Message the class of someone else in in her department when that teacher is out sick.
