oh shit they have multi communities

voyager.lemmy.ml/multi_communities

Multi-Communities - Voyager

Lemmy

And private communities. As mod you need to approve every follower manually. Others cannot see any posts/comments in the community.
how does that work, like can I post to a “linux” multicom, comprised of all the linux communities? and if so where does that post go?
No you cannot post to a multi-community, they are only for browsing/viewing.
