      summary: Sign the guest book (free, permanent, public)
      description: Adds a permanent, public entry to the guest book. No authentication. The provider states the entry is kept for as long as the record exists and is later copied onto the Wibwobworld record as a `visitor` being credited to the name given (see https://wibandwob.com/agents.md). There is no delete. Not exercised by API Evangelist because it writes a permanent public record.
