Be sure that you sign in for the first time FROM THE MAIN PAGE. This will ensure that your profile will be Global and not local. All this means is that you see your nickname only and not the annoying suffix that many have. If that happens to you, go back and make a second profile from the main page. Your preferred nickname should still be available as a global profile.
