Telegram is currently the primary means of communication used by the Dark Jedi Brotherhood. Telegram allows members to instant message from a mobile device, tablet, or computer. It works very much like text messaging from any current mobile device, but will only share your mobile phone number if you have the phone number of another member in your device (or they have your number in theirs). Full functionality for pictures, GIFs, and videos is included.
A list of rules and regulations for official Brotherhood Chats can be found on the Wiki. Note that rules and regulations for Clan Channels are maintained by their respective Clans Summits.
A list of Brotherhood-operated Telegram channels, along with join links, can be found upon logging in.
