i am not a chatter so i cant really give you specifics. havent been for years and i know chat has changed since i have been there. but no one has responded so i wanted to drop you a line. i know when i was going, the topic of chat was whatever people felt like talking about. some people open their own rooms and it is just a social gathering...i think that is what coffee house is. some people pick topics to chat about. if you go to the community calendar under the forums heading above, you will find many scheduled chats based on diagnosis or specific topics as well. hope this helps.
