Off clears the room for every viewer and removes every chat surface from the page; it stays off after a restart until you turn it back on. "Only during shows": open while live, messages clear when each show ends. "All the time": open between shows too, and the room keeps its messages (up to 200) until you clear it or the service restarts.
Listeners' reports for this show (and the last one, until the next show starts). Kept in this service's memory only: a restart drops them.
Shown in the room with the STAFF label and your staff name. Only while the show is live.
