Go to "my settings" on the right side of your page. Click "Account" on
the left side of the page. This will allow you to change things like
your display name, where you live, and it gives you the option to hide
your gender and age. Please note, changing your display name does not
change your account name. Whatever you signed up with, will remain the
same. Only the display name for your personal page and the forums can
be changed. (IE John Smith, display name Bob, account name will still
list John Smith).
