++- **A site assistant** is an inbox whose people do not answer (`handoff` off in its settings): Vibe answers alone, there
++  is no "Talk to a person", Vibe is told nobody else answers (it points to the contact details in the instructions
++  instead of handing off), and when it cannot go on the visitor is told plainly. An inbox needs Vibe or its people.
++- **Ratings:** a resolved conversation asks the visitor "How was this?" (👍 / 👎, then a line if they like:
++  `POST /rating { token, rating: 1 | -1, comment?, conversation? }`); the people see it in the list and the
++  conversation, live (`inbox_rating`).
  - **Nobody misses a visitor:** when a conversation starts waiting (the visitor asked for a person, Vibe handed off,
    or Vibe is off) or a visitor writes while it waits or is open, and none of the inbox's people has it open live, each
    of them (or only whoever took the conversation) gets an OpenVibe notification through the Network
