Just tried it on my iPhone and the chat requires Flash, so it won't work there. You might have better luck on other platforms.

Digging a little deeper, I wasn't aware that chat still requires Flash and found out that it does. Not for anything on the screen, but on the backend, in how the client (your web browser) talks to our server. This is an unusual use of Flash, so it's the reason I wasn't really aware of it before now...
