Thanks for the feedback!

Regarding your suggestion: To be frank not sure I get what you mean. In order to send a message using Hive-Mail the sender needs 1) the recipient account name, and 2) the message to be encrypted. The recipient in turn needs three things to perform decryption: 1) his account name, 2) the encrypted message received from the sender, and 3) his own Hive-Mail Private Key. So the sender does not need to have a Hive account, but the addressee does. This is due to the public key system used by Hive-Mail.

So even if such instructions were to be added somehow, you still wouldn't be able to send encrypted messages to a recipient who up to that moment still doesn't have a Hive account.

That said, I think I'll add to the Hive-Mail website a link to the Ecency app so people who still don't have a Hive account can get set up.
