And even though it says the chat is not registered, you can still access the chat throught the site and it's usable. It's just that when you type something, you get that message, but the chat still works.

About the registration part, you can do much about that. The actual chat program thingy is what needs to be registered. Only Kevin or one of the moderators can register the chat for simplymaya, which I know he plans on doing

Hope this helps,
George
