It's important to tell your users when you stream to ensure that you will always have your audience ready waiting for you. The Broadcast Schedule helps you achieve exactly that.
If you go to "My Profile", you will find the Broadcast Schedule widget. Click on the switcher next to it to enable it, and next you will see all the days and different time slots. Select the ones you usually stream on, and hit "Save & Publish". Now your stream schedule will be posted in your profile for everyone to see, so your fans will ever miss any of your shows!
