How do I change my user name?
You can change your User Name by click on you avatar in the upper right corner of your screen. Once you click the avatar, there will be some choices pop up. One of those choices looks like a person, on the far right. If you click on the person, it will open up your preferences. One of the preferences will be your User Name with a pencil icon. If you click on the pencil icon, you can edit your name. Make sure to save it when you have made the changes
