As an Admin, you create new Learner accounts in a few easy steps. There are actually two ways to do this.

The first option, at the admin menu at the left click on the "Users" - "+ Add New User" button.

Alternatively, click on the "Learners" tab (as seen in the screenshot above) and select the "+ Add User" button seen in the upper left.

Lastly, fill out the information for the new account (full name, email, and tags).
 Of course, please make sure to click on the "Add user" button to finalize the process.

An activation e-mail will be sent automatically to the new user, asking him/her to set up a password for the account.
