If you want to change your MTA Forums username, you are now able to do it yourself without the need of asking a Forum Administrator for help. You can find the option for changing the forum username (also known in IPS as Display Name) in the Account Settings, located in the collapsible menu in the top-right corner of the page (near your forum avatar and nickname). You can also visit this link to get to the username change page directly: https://forum.multitheftauto.com/settings/username/
