Its been existing for about three weeks already but it is never too late to join it: the Telegram Group for Transcendence/Telos (and XBTX) have been set up by ZenH2O and you are free to join it.

If you feel Discord is just not enough or you just prefer Telegram otherwise, this is a good option and as far as I have checked it, there is usually quite a load of unread messages waiting there every time I remember the thing exists and check it.
