Some LoRaWAN Enthusiasts, mostly, but not only around Fablab-Nuernberg use a Telegram Channel to discuss about LoRa and TTN Topics.
Channel-Link: https://t.me/lorawan_nordbayern
There is also a TTN Comunity Nurnberg https://www.thethingsnetwork.org/community/nurnberg/
but i am no core-Member of this comunity, so i cant add this channel as Communication channel.
You may take a look to this ( Low traffic ) Channel ?
