When a coach or athletic manager press the pencil edit a practice or game, and then press "save", a notification is automatically send to parents regardless of whether:

1. Any changes have been made
2. The calendar date is in the past

From a UX perspective, many people simply press save (instead of "x") to get out of a popup. While there is a send notification checkbox in the popup, it's very easy to miss.

I think there is a simple way to remedy this situation - if no change has been made to the event and/or the calendar date is in the past, and the user presses "save", have a warning box appear that says

"Are you sure you want a Notification to be sent?" 

<Yes>  <No>

If the user selects Yes, then the notification will be sent. If they click No, then the system should not send the notification.
