Right now the options for email notifications/reminders appear to be limited (and unclear).

Are they sent an email upon initial booking? What if we decide to cancel the meeting? Are they sent a notification of cancellation?

Right now, the only email that I see is a reminder email, though it's unclear when that is sent (text says: "Send reminder at (in hours)". No idea what that is supposed to mean. Also doesn't appear that we can edit that email so I have no idea what they're being sent.
