How do I make changes to my profile?

Sign into your account and click "My Profile" (you'll see it in a few places on the home page, they all take you to the same place). Once in your profile, click on "Update Your Profile" on the right hand side of the page. That will take you to the page where you can edit your name, avatar, personal bio and more. After you make changes, be sure to input your password to confirm them.
