For anyone who doesn't know, a lot of us are using the SmartGlass app and the Destiny mobile phone app to communicate with each other. SmartGlass allows you to send and receive messages on Xbox live from wherever you are, along with some other cool "universal remote" features when you're close to your Xbox One. The Destiny mobile app is good for posting on the clan page wall and checking the forum. It makes communication much easier, especially when typing out messages on Xbox Live.
