Is there a way for a user who is currently logged off to know the difference between a message that is buffered while a user is logged off from when the user is logged on and receives the message.
If X sends Y 3 messages while Y is logged out of QBChat and then Y logged back on. Could Y be able to tell the difference between messages received while Y was logged off then messages recieved when both X & Y are logged in?
When user Y will be online he receive 3 messages at once.
