Can large groups of users be bulk imported (username/email/password)?
Is there a way to bypass the whole invitation/signup process and simply bulk enroll a large group of people, assuming I have a spreadsheet of usernames, email addresses, and passwords? It would be great if I could just send people pre-assigned information so they could just login right away.
