Usually when an experiment implements a chat it's needed for the experimenter to be able to monitor what's being said in the chat rooms in real time, to prevent or at the very least mitigate certain actions (like improper use of language, harassing or sharing identifying information). AFAIK there's no documented way of doing that as for now with otree. Maybe in the future is implemented, but in the meantime, what would be the best way of listening to all the messages?
