D8 keeps logistics legible
D8 — Communication is the domain behind booking-scoped messaging: dietary updates, arrival tweaks, and accountable conversation. It exists so neither side has to trade personal contact details to get a meal on the table.
Boundaries matter
Stay on topic, redirect off-platform payment requests, and report coercion or harassment. The thread is part of the trust graph, not a private chat app bolted on the side.
Stay in the loop
messaging-with-boundaries and day-before-coordination are the etiquette companions.
