Click "Add User" on the left in the dark column.

Enter first & last name of your learner, then you can add the email address or leave it empty and use the access code (If you have chosen the Access Code option then you will need to give them the code manually).
Click submit to save your new learner.

If you set up the new user with an email address they will receive an email with log in details.

I hope this helps you!
