change itunes nickname

iTunes question?
Okay, so when I'm reading things about how to do things in your iTunes tells me about the options that I have in my iTunes. He always says "Go to your account page and click but there ________" __________ button on my account page. The only buttons I have in my iTunes account page are: Edit account info, edit the payment information, change country, purchase history, edit aliases iMixes management, managing comments, manage my alerts, allow my iTunes, reset warnings. You can not change anything else. Is this normal?
can be a bit more specific on what your asking you to click?
