Would be great if we could choose the email address (or have it the same as our username) so that it is easier to remember.
Then to reduce the chance of spam emails, we could then have the ability to choose what email addresses the Boxcar email can receive from.
E.g. i can chose my Boxcar email address to be "MyName.bxc.io" and it can only receive emails from "MyNamy.gmail.com" etc.
