Just drafted a couple new nips for private groups (rebranded as "closed communities"). I'd love your thoughts:

GitHub

Add closed communities by staab · Pull Request #875 · nostr-protocol/nips

This is an attempt at superseding #706 and incorporating existing NIPs for community definitions and member lists. The design is worse in many ways...

The goal is to introduce as few new concepts as possible, instead composing existing functionality together (kind 30000 for member lists, and building on nip 72 communities). The benefit of this is that we now get hybrid communities, which can be partially public and partially private, which could have some interesting use cases.
