I'm not sure how many of you all are active on Telegram, but there are many open source groups and communities there, such as Fedora, LibreOffice, Firefox, NextCloud, and plenty more. I created a MusicBrainz Telegram group and reached out to a few people in open source communities I'm involved with there to check it out.
It's still small now, but I figured I would share it here on the forums in case there's any other Telegram users who would like to peek in and say hello there. Hope to see you there!
