Hi I have added new users but they cannot log in. What email and password should they use?

Hi nafula:

If you go to the Gear Icon, and Manage Users, you can see the email address you setup for the user.  Confirm with them that this is the right email.

Once created, the user will get a prompt to create their account and set their own password.  If they don't remember it, they need to use the 'forgot my password' link at the login screen.
