Ever needed to send yourself a file, but didn't feel comfortable logging in to your email or dropbox account? Ever tried to talk your parents through emailing you a file as an attachment? Yeah, me too (and apparently also a lot of other people [1]), so I hacked this small sinatra app together over a few weekends [2].
Suggestions, critiques, and pull requests are welcome!
