I’ve thought of something like this for a homeschool co-op group.
Discussion
The whole, or only the private posting?
Not really sure. I had thought a relay locked to only approved npubs. Then all the kids and parents could chat about the co-op or whatever without any randoms. It’s probably already a thing.
What do you mean?
That is what I was thinking.
If you want to play around with it, just spin up a haven instance. Then you have everything for your group.
On the other hand, the original idea was, to really store the data privately. So you could use any relay.
