RSVP by link. No app needed.
Not everyone wants another app. Organizers tap “Share RSVP link” on a play day and drop it in the group text. Friends tap it, type a first name, and pick I’m in, Maybe, or I’m out from any phone or computer. Their seat shows up in Kongvene marked “via link,” and organizers get the usual heads-up. Only a first name and an answer are saved, and links stop working two days after the game. See how it works.
