Our Mail to the Future website was chosen "Incredibly Useful Site of the Day" by Yahoo Internet Life.
They say: "Time travel is the stuff of science fiction, but you can send an e-mail message into the future at Mail to the Future. Register for free and you can send mail to yourself or to others at a specified date and time in the future. You can also review messages that are waiting to be sent in your 'queue.' Simpler and easier to use than a full-blown Web calendar, this site sure beats tying a string around your finger for a quick reminder."
