I am hoping to use Google AppEngine on a non-profit open-source project. To help me get familiar with AppEngine, I made a very small, simple webapp that sends a short message to any signed up users when they make a HTTP-GET request to their assigned URL. It’s useful if you have a very long running simulation or compilation that you would like to walk away from but be notified when it completes (or errs.) Assuming the email address used for your Google Account is also the one used on your smart phone, it basically mimics SMS without the headache.

The message should be shorter than 78 characters. Anything longer will be truncated. The message will be the email subject. To (feebly) prevent a quota DoS attack, each account is limited to 100 messages a day.

P.S. I learned only minutes ago that AppEngine apps cannot receive email from custom domain addresses, a feature I think my non-profit app will require. FAIL!
