It would be a handy feature to be able to be notified via email whenever a turn took place on some team games, especially multi group games. Like each time one player takes a turn in a quads and it switches to another player, you can be notified.
This would be helpful for those who are the 'lead' on a team game for their team mates. So they can be notified when it is a player's turn, so they can log in and analyze the situation and give them team mate advice on their turn. Or to be notified when an enemy has taken their turn so they can log in and get a snap.
Announcement: It is now (player X)'s turn in game (XXXX)
