When you start a Rabbitcast, you are in control. You will see a red remote control icon in your toolbar, and the circle around your chat bubble will turn red. Also, you will see “You are controlling the Rabbitcast” in the top, right-hand corner of the sharepad (if it’s open).
To give someone else control of the Rabbitcast, click the red remote control icon in your toolbar. The remote control will turn white and will then be visible to everyone. Someone else can then take control of the Rabbitcast by picking up (er, clicking on) the remote.
