This is my November Startup Sprint[0] project, inspired by a StackExchange question[1] from this HN thread[2]. The idea is that the app creates a unique email address for you, and any emails of the form "Lunch with Bill Tuesday at 12:30" that you send to that address will be added to your Google Calendar. I'd love to hear what HN thinks of it. Much thanks to HN user riskish for his design help.
