The chat rooms will be created by admins, and the current mods/admins would monitor them.
Would the chat rooms be assigned a specific topic by the admins who created them as well, or would the topic be left open-ended? In that sense, assuming that the former is made true, users are almost limited in what they can and can't talk about.
An idea that has been suggested is adding chat mods (it has worked on other websites), but they don't like the idea for whatever reason.
A trust issue, perhaps? I know that I'm always paranoid about doing group work since I often can't trust the other members to do their jobs.
