There are no signups on nostr
Discussion
No I mean if you want to “replace your email inbox” how do you sign up for sites and apps that require an email address?
Just use nostr.
Not helpful
Two scenarios I can think of:
1. The website would have to create a nostr account and you'd provide your npub for them to send you "mail" to.
2. If the website hasn't created a nostr account, maybe a bridge can be created that forwards any emails sent to an email address to a nostr inbox.
