Keys

Paste the key to be able to take down anybody’s idea. Everyone can already take down their own, so this is only for tidying up after other people.

The key is only checked when you actually take something down, so a wrong one looks fine here and fails there.

Sign out and forget this device

Signs this browser out completely: your name, this device’s family id, your email and any admin key, all removed, so the next person to pick up this phone genuinely starts as nobody rather than as you. The shared board is untouched, and so is anything you’ve put your name to on it. The page reloads into a clean, signed-out state.
