The nostr protocol should integrate something that allow Discord-like "channels" - maybe call them doors - tied to public keys. It would be a great integration for dynamic chat rooms and a great harkening back to mIRC. Let the naming convention for channels be whatever is typed between double hashtags, i.e. ##first door## for instance. The user/public key can carry these "doors" or "channels" with them, allow other public keys in, moderate them, remove them, etc.
