We have switched to a new chatroom software provider. You are on the correct site. It just looks a lot different.
You will see pop-up windows on each page allowing you to access the new digs.
Use the pop-up window and select Public Chatroom and a second box will pop-up allowing you to chat. If the room assigns you a made up name, click on the tiny pencil in the upper right corner to change
your name.
In the settings area, the gear beside your name, a drop down window will also allow you to mute the sound effect associated with comments.
(You'll hear what I mean shortly after you arrive.)
