Agreed and I am on chat now and my name is not up on whos chatting. Also it seems to be very slow on the update as lotsa peeps on chat may be gone or changed and the Whos Chatting bit doesn't change.
Just spoke to "brodie" over at everywherechat.com, and I am told that the chat indicator is temporarily unavilable because it is under investigation for causing too much strain on the database server said it shouldn't be too long before it is back, I'm sure you can live without it for a while
