@mastalab has its own #peertube channel at https://peertube.social/accounts/mastalab/ with useful content, like
"How to upload a video to peertube"
Better to use the channel :/video-channels/[email protected]/videos
path to add to the url of its instance (if it follows peertube.social) in order to subscribe to the channel.
Following an account (in #Peertube) doesn't seem to be working yet.
mstdn.io is one of the instance in the fediverse. We're an open-minded generalistic instance. Learn more here!
