Start a "Who's in?" from Play or Home: a name and a day is all it needs (add a course, the game, when answers close, and how many spots if you like). Share one link: people tap In or Out, signed in or with just their name (and a handicap on a net game), no app needed, and everyone with the link sees the list. Past the spots, an In goes on a waiting list and moves up when someone drops out. When you're ready, Start the round opens the setup with everyone who's in already on it. Next week, Run it back starts a new outing from this one; a crew's link stays the same every week.
