To edit your personal profile information, click on your profile image in the top, righthand corner of the page. Select “Personal Settings” from the drop down.
Step 2: Edit Your Personal Information
Once you click “Personal Settings” you’ll be able to edit your personal information as well as your privacy settings. Just make sure to click “Save” so you don’t lose those changes! If you changed your profile image, then you'll need to click the "Save" button under that instead.
