Tripod is currently using its own member-oriented message system. Right now, all Tripod members can be involved in all message boards. Your participation in a message board helps create and sustain an ongoing conversation or debate.
People read and respond to others' posts over a period of time.
Chat is real-time live interaction. The people you are chatting with are there now and response is usually immediate. You will be taken to a screen where you may enter the text you would like to post. Please stick to the topic. If you're worried about people not finding your page, make sure you have a current profile posted and save the blatant self-promotion for the talk show circuit.
