Srilakshmi.murthy,
Can you explain this issue in more details?
When the user joins the room, a public message is shown in the user screen.
If the admin/moderator activates moderated-Chat in a room, everybody in current room will be notified with the message "Moderator activated moderated chat function. That means that your messages won't appear until a moderator approves it." After that, newcomer to the room will be informed with the message "This is a moderated chat room. That means that your messages won't appear until a moderator approves it."
