Prevent younger players from being able to receive email
Young players (e.g. all under the age of 16) should not really be directly receiving email from adults.
As a team admin, I would like to protect the young people and the club by preventing them from receiving email from "the system". It is not enough to leave the responsibility with the sender, as "select all" may silently select a young person.
This will also prevent adults (parents) from creating a "mixed" account that represents themselves and their child in one "person".
