You can now send a private message to a user.
It's still only one-way, but I'll be eventually adding a chat-like function for replies and private conversation. Something like:
I still have to add email unsubscribe for the feature, and other details, but it should be working so enjoy!
it would be really cool if messages would be encrypted with my public pgp key and when the service could not read them in the sense that the message is really private (: I already trust you with my hard earned satoshis on this site (:
Woah - that would be amazing! I'm totally looking into this. Users can add their pubkeys to their accounts and messages could be automatically encrypted. You would have to decrypt each message locally.
I could also look into using a lightning node key, or bitcoin key to do the encryption. LND already supports message signing and verifying https://github.com/lightningnetwork/lnd/tree/master/lnrpc . Great idea!
