party²
Plan something with more than one part. A wedding with a rehearsal dinner and a brunch, a reunion spread over a weekend — one guest list, one page, and everyone knowing which bits they're actually invited to.
Happening publicly
Events with parts
Each part has its own time and place, and its own idea of who it's for: everyone, opt-in, invite only, or hidden from guests entirely for the setup crew.
Invite a phone number
No account needed first. Paste in numbers or addresses; people get a link, prove it's them with a code, and they're on the list. Say how many extra guests each one may bring.
One wall per event
RSVPs, questions and replies in a single thread, three levels deep, with reactions. Talk about one part without bothering everyone else.
Photos afterwards
Guests add their pictures to the event. Location data is stripped before anything is shown, so nobody publishes their home address by accident.
