Tell us where you walk, and we'll send an invite when your city's turn comes round.
Invites go out in waves, a city at a time, so this isn't a queue you get to the front of by asking early. A feed is only worth opening where there are enough posters on the walls to fill it, which is why the city you name matters more here than the date you asked.
The app is iPhone-only for now. If you carry an Android, ask anyway — you'll be first to hear when it lands.
Your email is only ever used to send you an invite. It isn't a mailing list, and the privacy policy says what happens to the rest of it.
Thanks — that's on the list. Invites go out in waves, a city at a time, and your email is only ever used to send you one.
