Help: How do I automatically post broadcast to Twitter or Facebook?
Log in and browse to your settings page. Find "Connect" in the list of settings and you will find a number of social networks to share your broadcasts to.
Click on the service you would like to connect to, such as Facebook or Twitter, and follow the instructions that appears.
When connecting to Facebook, your broadcasts are automatically posted to your personal wall as default. You can also chose to share to any other Facebook page that you have admin rights to. If you connected to Facebook before October 2011, you may need to disconnect and reconnect in order to see all pages you have rights to.
If you want to choose directly in the app on your phone whether to share your ongoing broadcast or not, uncheck the box next to any of the connected targets on your dashboard and you'll be able to share manually instead of automatically.
