The gavel sits with whoever's birthday is coming up next, and passes on its own once that day goes by — no need to pass it manually. Whoever holds it gets a 1.5× multiplier on their stars. Add people in the Birthdays section below and they show up here automatically.
Everyone joins with a confirmed email link, then claims their council name. You can edit names and birthdays here.
To avoid losing anything: tap Save data file now and then. The live version saves automatically to the shared cloud row, and this gives the admin a portable backup.
