There are two chat rooms! Click the arrow in the top of the chat room space to the right of Melanoma Chat. a drop down window gives one the options of :
OFF TOPIC CHAT
It doesn't work as well as the old two chat room set up did. If you jump from one chat room to the other your screen in the newly entered room is wipped clean. Also the window no longer shows you who is in the other chat room like in the old days. I have complained numerous times about the difference, but received no response from the MRF about it.
