CHAT: Shortcode parameters available?


When placing chat in a page using the "Insert Chat" button, if I attempt modify any parameters, the shortcode that appears is always the same with no parameters other than this:

[chat blocked_ip_addresses_active="disabled" ]

I'm not concerned with troubleshooting why the insert button doesn't include the parameters - I just want to know the parameter for naming the chat group. For example, I tried some guesses like:

[chat title="MEMBER CHAT"]

But that didn't work. Can anyone tell me the code to name the chat?
