Question: The issue we have is that they don't like to receive a separate email for each SCORM package. Is there any way to register someone once for multiple content items so that they receive only a single email with multiple links within?
Answer: Each course invitation would need to be sent in a separate email. The only way to send multiple invitations to a user would be to generate multiple public course URLs and send them via an email from your domain. Please note, that they wouldn't be registered for the course(s) until they've entered their first/last name and email address.
