It's ok... dont feel like you have to keep in touch with the talk. Sometimes chat is very fast and very confusing... sometimes I just dont bother and concentrate on something else, just saying hello when somebody enters the room... other times i wait until i understand what is happening and chip in then... other times, i am content to watch chat go by and keep quiet. don't feel pressurized to act ina certain way in chat, people will understand and respect you no matter what you decide to do to feel comfortable in chat.
