Please note that Markdown does not work in room descriptions. However, it will work in chatroom guidelines, if we so choose. An example of a room guidelines modal is below:

Is there anything that we think needs to be in this modal? While we haven't had chat problems recently, there are historic one-off cases of users being disruptive, to the point of driving other users out of chat. (Yours included.) We could also decline to set room guidelines at all, in which case we would only have the general chat modal.
