Hi It already happened twice that a user (Teacher) deleted a Team. I Think it's because of the place where you can do it. In more options ... you can leave a Team and delete it. Maybe it's the translation (Dutch, "Het Team verlaten" or "Het Team verwijderen") that a user don't understand the difference between the two possibilities. My suggestion would be to place the "delete Team" in "Settings" UX wise. So the "normal" user can't delete a Team as easy as it is right now.
