Hi there!

In the right top corner you have ';Options';

Click on it and in the bottom of the pop out is ';more options';, click on it and the next page is either a login or straight away the ';more options'; page. In the top is ';Manage your Account';, click on: ';view and edit your personal information';, next page, in the top you will see that name you wnat to change, under the first bit, under your birth date is';Registered Information';, click on that. Now in the Top you see ';Name'; and your Name with behind that in blue ';change';, click on that, finished.
