The Statement of Accomplishment uses the full name that was provided when registering for a Lagunita account. If you need to change the name as it appears in the Full Name field, click on the downward facing arrow to the right of your username in the upper right-hand corner of your screen and select Account. Here, you can update the "Full Name" field. When ready, hit the enter/return key on your keyboard and your changes will automatically save.
Once the course has ended and Statements of Accomplishment have been generated, no further changes can be made to that particular Statement as Accomplishment, as it is not possible for you to re-generate your Statement of Accomplishment. If you would like to make sure future Statements of Accomplishment include your preferred name, you will need to make sure the full name in your Account Settings is updated before the Statement of Accomplishment is generated.
