Offer HN: Try out my dead simple email reminder tool (enagme.com)

I wrote this tiny app one night in an attempt to remember a friend's birthday. It worked well, and since then I've been using it to remind myself about lots of different things on a day-to-day basis. I figured I'd share it with the HN community to see if anyone else found it useful. Feedback is welcome (either here or via the form).
