Only Admins can add new Users. Go to the Admin section and click on Create User.
A Modal Window will open allowing you to Create a User. The first tab allows you to add the User Information. The second tab allows you to assign one or more Roles to the User. You should set up Roles before you start to add Users.
The second table allows you to select Roles. In this case there are only two roles defined, Admin and User. When you define a Role you can set one Role to be the default Role assigned to new Users. In this example the User Role is set as the default Role so that one is automatically checked when you click onto the Roles tab.
Once a new User is created that person will be sent an email with a login link. They will need to click the link and then we immediately need to set up their own password. Admins cannot create passwords for Users for obvious security reasons.
