Follow these steps to change your default username:

1. In the right-hand corner of the main page, place your cursor on your username and click on the “Settings” button.



2. In your settings choose Username field and change your current username to one you'd like to have. 



3. Scroll down and press the button "Save Changes". If preferable username is already used on the platform, you will get a notification saying "This value "LinLin4" is already used". 

In this case try to use another one.
