When you first create an account on Steam-Aid your default display name is your first name. If you don’t want to use your first name you can easily update it.
 
Here’s how to change your display name:

• Log in to your account
• Go to your account settings page by hovering your mouse over the profile image on the top right of any page
• Click on “Settings” in the menu
• Once on your settings page you can change your display name
• That’s it!
