has not been a problem (yet). MVP of this feature for now, don't want to over-engineer it in the beginning. 'username and email' because you give your username to the services that integrate notifo, and the apps have a chat feature so you can send other users messages by using their username. we need the email to reach the user for things like announcements, password resets, and now notification emails.
