I'm trying to use a shared calendar to allow users to keep track of the availability for set of laptops. I'd like them to post an appointment to the calendar when they want to use the laptops, but I would like an alert sent to me when they post the appointment.

Right now, I've created a rule that sends me an e-mail when I post an appointment to this calendar, but I can't get it to send an e-mail when another user posts an appointment. Any ideas on how I might be able to get this to work? Thanks in advance for your help.
