Newsletter
The first mention gives the date, the hours and the project list with capacities, and says when the sign-up opens. The second mention opens the sign-up and the shirt order with its deadline. The last call is the sign-up count, the shirt pick-up time and the morning schedule.
Social
Save the date is the date and the project list. The reminder post the Friday before is for the signed-up: meeting time, location, what to wear and bring, lunch arrangements. The day-of post is a photograph from the morning send-off.
Sunday Announcements
Announce it two Sundays before with the sign-up open and the projects that still need people. The final announcement is the Sunday before the Saturday: the meeting time, the shirt pick-up and the projects still short.
