Well, THIS is a problem.

Well, it's official. I HATE CHATANGO. Now my messages won't go through! (I'm not banned.) Whenever I send a message to the chat, it shows up on my screen, but noone else sees the messages, and when I refresh, they're gone. What is this?

It seems an IP very similar to yours was banned. The IP was an anonymous user who had been asking for koolkid's password via Chatango. This my be the reason for the fact that you can't chat.
