Virtru, a new email plug-in, could make it a lot easier to send an email securely.
We've all done it. That horrifying moment when you press "send," and realize that picture of your face photoshopped into a child's dinosaur costume went to someone with the same first name as the person who was actually meant to receive it. (This is a true story. It was only funny after 24 hours of extreme shame.) That's probably not the worst thing that can happen in the history of the email reply function, and probably not the worst that will.
