If you're talking about live, then you will see a tab that says, "chat" towards the bottom middle of the screen.
Here is a link to the screen shot because I refuses to be uploaded here for some reason.

(All right, I hope you can view this because there have been some odd problems resently with this.)
Groups have the chatroom function available, but most seem to just use the Notes function for that.
It seems like no one ever uses the group chat rooms for some reason...
I don`t know how to send a comment to chess.com staff,this is the best i can come up with.I apologize if this is improper use of the room. So...I just got a message when i logged on that restated the fair play policy,never happened before.so it must be because of recent multiple disconnections.Because i am presently on an extended road trip,McDonalds is my internet provider.They have cost me many rating points through disconnection.Just my luck,it will be very easy to prove disconnection wasn`t intentional since over 90% happened in Winning positions ! The worst part is most of the time i reconnect in a winning position but with only 30 seconds left. Sorry for creating a situation where unsportsmanlike play is suspected,nothingnew.
pls tell me where i can find the chatrooms on this server
