not sure what you mean.

if you mean the weekly chats doc john did only he can answer to that.

if you mean the chat rooms at the top of the page

as far as I know they are still there, at least the option is still listed at the top of the page in the menu bars.

I just clicked on whos in chat and it says zero, so at the moment of my typing this no one is in the chat rooms.

whether the chat rooms are still active or not I'd have to say your guess is as good as mine.

check with doc john or one of the moderators. they will probably know more than I do about the chats and chat rooms.
