Meetups and shared rides

In your event, open Meetups and choose Propose. Add a place, a time and how many people fit. Everyone with a ticket can see it.

Open a meetup and choose Join. You get its own chat with the people who joined. Leave it any time from the same screen.

Meetups marked as official come from the organizer. The rest are proposed by attendees, so agree on the details in the chat.
