Creating a MySQA Username
    A username is the unique name that you use to identify yourself on MySQA.
      You sign into your MySQA account with your usename and password. When
      you activate your account, choose a username that you like and that you'll
      remember.
    
    
      When creating your username please follow these tips:
    
    
      -  Create a username that contains letters and numbers only and is between
           6 and 10 characters.
      
-  Do not include spaces, tabs, email addresses or any special
           characters such as @, &, ', (, ), <, or >
      
-  Do not create a username that is related to personal information
           (for example your name, your birthday, or the town you live in).
    
    Note: If you received the message 'You have entered a username that is not
          allowed', you may have included a character that is not allowed in a
          username.
