What an excellent question
E-mail protocol is as described in the Regent's guide. It's fine to call it 60 or 60.5.
Your heading should read: RoE; (turn), (action type), (involving), (fitting title)
Example: RoE, turn 60, dispatch, WIT - IHH, cede spiritual supremacy to OA
Don't worry, we'll remind yall tirelessly as the game progresses.
