It's easy to stop your live-stream broadcast, as the place to do that is in the same place as you start the broadcast.
Once you have clicked on the Start Streaming button, to begin your broadcast, the button changes to a Stop Streaming button.
Click there to end your live-stream.
NOTE: IF YOU DO NOT PRESS THIS BUTTON, YOUR STREAM WILL CONTINUE TO BROADCAST, EVEN IF YOU HAVE CLOSED THE CHERRY.TV WEBSITE!!!
