No ads, ever
Parents see your sheet and nothing else.
Every name shown
No paging through ten names at a time to find who is coming.
Parents fix their own
Each family gets an emailed link to change or cancel. No passwords.
A day-of list
Everyone A to Z, students with the parent who signed them up, and a printable check-in sheet.
Kids, helpers and donations
Ask for a child's name, a time slot, or how many cupcakes, each in its own place.
