- Every Monday you're paired with a stranger, never the same one twice if we can help it. Odd numbers make one trio.
- Each day (UTC) you each write one message, up to 280 characters. No edits.
- A day shows once everyone has written. If someone skips, nobody sees it.
- Others see only your made-up name and color. Your email is for signing in and pairing notices.
- Each week's messages are deleted when it ends.
- Two weeks without writing and you're paused until you ask again.
- Reporting someone ends the pairing at once and sends it to a moderator.
