I somehow missed the existence of https://gup.pe/ – a new(ish) group tool for the fediverse.
I haven't used it yet, but from its description, anyone can create/follow a group, and then be notified of all messages that @ that group. Sounds really cool!
@codesections this seems like a super cool idea! Kinda like mailing lists for mastodon
Fosstodon is an English speaking Mastodon instance that is open to anyone who is interested in technology; particularly free & open source software.
