 The goal of this NIP is to create moderator-approved public communities around a topic. It defines the replaceable event `kind:34550` to define the community and the current list of moderators/administrators. Users that want to post into the community, simply tag any Nostr event with the community's `a` tag (See [NIP-33](33.md)). Moderators issue an approval event `kind:4550` that links the community with the new post.
