The shifts, who said yes, and who turned up.
An art walk with sixty-three artists needs a welcome tent, chairs, and somebody at the corner with a map. This replaces the clipboard and the group text.
Three things in one screen: the shifts you need filled, the people who put their name down, and who actually turned up on the day.
Say what needs doing in the words a volunteer would understand: Welcome tent, hand out maps, not Position 4.
Then the day, the hours, and where to turn up. That last one is the thing people ask about most, so put the corner or the door in it.
When that many have said yes, the shift shows as full and stops taking names.
0 means as many as will come, which is right for a litter pick or a set-up crew where more hands are simply better.
Every sign-up is emailed to the address you put here, so you know without opening this screen.
Use a shared address if more than one person is organising, or you become the only person who knows who is coming.
Put it in a post, an email or a newsletter. It is also on the tour, under Lend a hand, for anybody already walking.
The page only shows shifts that still need people, so nobody signs up for something that filled an hour ago and nobody has to be told no.
A volunteer checks themselves in from the email they were sent, so the common case needs nothing from you.
A cancelled sign-up is archived rather than left sitting in the list, so the roster you are holding on the day is the roster.
Off keeps the shift and everybody on it, and stops new names. Use it when you have enough but want the roster intact.
Beyond a name and an email you can ask whatever you need: a phone number, a t-shirt size, whether they can lift, whether they have done it before.
Type the question and pick what sort of answer it takes. What they answer sits under their name in the roster.
