@Andrii where on the Fediverse can one establish (optionally private) groups?
The social network of the future: No ads, no corporate surveillance, ethical design, and decentralization! Own your data with Mastodon!
Otherwise there is the megathread where you simply tag a bunch of people for a certain topic across the fediverse and talk about it.
You can also use hashtags and search for anyone else that uses the hashtag, that is how gab initially implemented groups.
