As officials must log on and accept the game again after changes of time, date or arena, it would be better if the information in the automatic emails state this.
Meny of our refs, especially the new and younger, forget to log on and accept and that creates extra work when we must contact them manually for the confirmation.
Please add more details
New text should be added after the listed changes, suggestion:
Please log on and accept or decline the changes listed above.
