Settings: Suggestion to set your Profile Settings - via the bungie.net website (web client), Top Right, Drop Down arrow next your logged-in profile name > Settings > Linked Accounts > Link your PSN account to get access to your PSN friends, etc > Notifications and Email > Suggested to enable PUSH notifications for all of the available options (this will push to the web client as well as the Companion App, which is handy for forum discussions and arranging meeting up)

Ways to enhance your Destiny Experience: 1) Official Destiny Website (via Bungie.net) - aka Web client - Has full functionality over the browser to access the Social environment 2) Official Destiny Companion App (downloaded via your mobile store provider) - Has most of the functionality of the web client in your pocket, including reviewing/switching your gear, forums and chat groups, etc
