If you would like to add Trainees to Mindflash without adding them to a course, you can do so on the Users page.
Select "Users" from the Left Naviation.
From that page, click the Add Users button.
Select the method you would like to add them: Individual or From Excel.
Once Trainees are added to the account, they will appear in the list of users you can access. Select one or multiple Trainees and invite to Courses. The first time they receive an invitation, they will be prompted to set their password.
Note: That passwords must contain at least 8 characters, one uppercase and lowercase letter, number, and symbol.
