I use the MyRockpile Community app on my phone every day - I can review questions, post responses or watch videos from anywhere as a result - are you doing the same?
If not then go to the Play Store or Istore and download the app called Discourse Hub. Install the app. When you run the app you get the chance to select the MyRockpile Community URL to set the Discourse Hub app to be the MyRockpile Community app.
Try it out - we think you will like it
