This is the chat box we used to have which I could no longer pay to have. But I did pay for it today, given the other one was not only causing some issues with page loading, but it also allowed those annoying strangers to PM you with silly messages.
The new chat is simpler, cleaner and looks better. You can register your name of course. It isn't as loud or have all the annoying smilies and so on, so I hope it works better for you.
