Sign up for Photojojo’s Photo Time Capsule with your Flickr account and every couple of weeks, they’ll send you some of your old, underappreciated, and probably forgotten photos from a year (or six months, if you’re a newer Flickr user) ago in a prettily-formatted email. Also, there’s a section in the email that allows you to write your future self a note that will be sent to you in six months. Cute!
