Not every website that uses the factchat gives the opportunity for switching between several chatrooms. You can find out if there are more chatrroms by checking if a "go to room" button is displayed between the "search" and "logout" button. If there is and you click on it, a list of chatrooms will open, where you can select the new chatroom. If you want to return to the previous room however, you need only to click on the "back to chat" button (bottom left).
