When a student is enrolled in the course, do they receive an email confirmation? Or can they be emailed?
No, no email confirmation is sent when a user is enrolled into a course. We are looking to add this as an option. If you are enrolling the users through the API, you could trigger an email to be sent using the SendMail command.
UPDATE: If a student has enabled notifications for "My enrollment status changes," they will be notified of the enrollment once the enrollment has started.
