Keep the chat. Move the roster out of it.

How a roster ends up in the chat

The Saltwater Creek Landcare group has 41 people in its WhatsApp group. Every month Ngaio posts the planting-day roster as a message: four Sundays, three names each, who brings the trailer. Then the replies start. “Can’t do the 9th, sorry.” “I’ll swap with Jack if he’s OK?” “Who’s got the trailer key?”

By Wednesday the roster is a puzzle spread across forty messages. Ngaio reposts a corrected version. Someone screenshots the old one. On the Sunday, two people bring trailers and nobody brings the seedlings.

That isn’t a WhatsApp problem. It is what happens when one place is used for two jobs: talking, and keeping a record of who is on.

What a group chat does well

WhatsApp’s own pages describe group polls, events with RSVPs, and sharing large files in the chat. For a group that meets once, a poll or an event is often all you need. The chat is also where the friendly part happens: the photo of the finished garden bed, the thank-you, the “running ten minutes late”.

Where the roster gets lost

• The latest version is hard to find. Pinning helps, but corrections still arrive as replies.
• Turns aren’t counted. Who has done three planting days this year and who has done none? The chat can’t tell you.
• Not everyone is in the chat. Some people don’t use WhatsApp, and some groups don’t want everyone’s phone number shared.
• Away days come as messages. “I’m away all of March” scrolls past and is forgotten by the time March is rostered.

Side by side

Using both together

The tidy answer is to keep the chat for talking and post one link to the roster. In FairTurns you add the planting days once, choose how they repeat (“Every second Sunday”), set how many people each needs, and press Fill. Each place goes to whoever has had the fewest turns. Pin the public roster link in the chat. It always shows the current roster, names and dates only, and nobody needs to sign in.

When someone is away, they mark it themselves, or you mark it for them if they have no account, and Fill leaves them off those days. If a change happens, you change the roster, not the chat; the link shows it straight away.

With Pro, people who have accepted an invitation get a reminder email before their date and can reply “I can’t make it” from the email. With filling by itself switched on, the next person in line is then asked. FairTurns doesn’t send WhatsApp messages or texts, so the chat stays useful for the last-minute “running late”.

A message that works: “Planting roster is here, always up to date: [link]. If you’re away, mark it in FairTurns or tell Ngaio.”
