Lemmy

I'd like to set up and federate an instance of Lemmy with the purpose of inviting friends and family. I imagine that they'd appreciate having spaces limited to family members where posting information or photos wouldn't erode their anonymity elsewhere in the fediverse.

Is there a way to make some communities private so that only those who are invited can view or post within them?

When searching, I only see one mention of private communities as a feature that isn't finished. But, that post appears to be 3 years old.

Thanks so much! I'm really enjoying the community here.
