Seems like the chat room doesn't work correctly or may have some browser incompatibility. When you first come into the chat room, the text window is blank and it's hard to prove, but I'm pretty sure when you greet someone that enters the room they see nothing even though the present members are typing. Something is definitely weird going on. Seems like folks want to use it; there are 5 in there now. But no text is flowing. I'm using Safari on OS Sierra 10.12.3.
