QR code → private chat

• sign in, say hello, and get a QR code.
• put it anywhere: a poster, a package, a note on a windshield, a for-sale sign, a text message. any device that scans it sees your hello, and you get an email.
• each device that scans gets its own thread with you, on that page, live & anonymous. a device that signs in gets email too.

anything you would rather not put a phone number or email on. to make a QR, sign in below. a device that only scans needs no sign-in.
