I have had an SMS and cell phone VIOP version of this in the pipeline. However, You gotta love a good email reminder. (210,000 messages!)
FutureMe : F u t u r e M e . o r g.
here's the story: two fellas started this so that you could write yourself a letter to be delivered at a later date. we've all had to do them in high school and college. it's sorta cool to receive a letter from yourself about where you thought you'd be a year (two years? more?) later. FutureMe.org is based on the principle that memories are less accurate than emails. we strive for accuracy.
