Chat noauth_login_message seems to be broken

Hi folks,

I'm putting a chatbox into a page and have set the "noauth_login_message" when creating it, however I am still getting the default "To get started just enter your email address and desired username:" login message when the chat is displayed.

Is this a bug, or how can I get it to display my own message above the login? Ideally, I don't want to capture e-mails at all - just a name - is there any easy way to do this?

Chatbox code below.
Thanks!
