I wish I could find it, some designer 4 months ago made a really great graphic explanation of how this would work. it’s not ideal tho, iOS and many other digital environments see a @ sign in the middle of words and assume email address, which is a known complaint about mastodon so it’s been avoided here, some nip 05 providers even offer email forwarding 😅 maybe we need to take a hint from bluesky and change to a period so you would be @bob.nostrplebs.com instead of @carol@nostrplebs.com I’m not sure the double @ sign here is technically doing anything
