I'm trying to follow https://github.com/nostr-protocol/nips/blob/master/05.md in particular at the section "Showing just the domain as an identifier" so I use _@tomgag.net in my profile's NIP-05 field. Basically I would like people to tag me with @tomgag.net rather than something@tomgag.net . Am I doing it wrong?
