Pickleball RSVP — who's in?

Field notes

The board keeps each response beside the game's date and location, with separate states for in, tentative, and can't make it. Guests can occupy a spot without entering the permanent player list, while notes preserve details such as arriving 15 minutes late or waiting on a sitter. The sample uses a shared password rather than individual accounts and shows the threshold logic directly: two players make a singles match and four make doubles.
