So I figured out how to tell Live Agent to use a custom page... (I think)

But when I switch to using a custom page, and the user initiates a chat from a Chat Button, the user is blocked by an "Authorization Required - You must first log in or register before accessing this page." message. I attempted to adjust the "Security" setting of the page, just adding all the roles to the page, and that didn't work.

So... how exactly do I expose that custom page so that any of our customers/users (i.e. The Public) can communicate via the custom chat page without requiring a login?

Thanks!
