Futuremail - E-mail With An RSS Twist

Just stumbled across this on Digg.com.
It's called Futuremail and it allows you to create e-mail reminders that are then stored and e-mailed to you on the date and time that you specify.
One of the features that really caught my eye was the ability to share your future e-mails in an RSS feed, which would be great for any collaborative or group projects you may be working on - check it out here.
