Post a comment on your old self from the future.
Wonderful tool (thanks BoingBoing, via Marc), which allows you to send emails to yourself at any point in the future — assuming, of course, the site, FutureMe.org, is still functioning and you haven’t changed your email address.
What is fascinating is to read other people’s emails (there’s an option to allow them to be viewable or private). One anonymous posted told her future self: “Dear FutureMe, I am a stupid bitch. I am writing this because I am drunk and feel that i need to tell someone how I feel”. Another: “Dear FutureMe, please buy me a G5. also, marry me a hott ethnic chick. yeah. oh, and dont die.”
