 * I am facing a bit of a problem since if a user forgot his/her password, then 
   a generated Number username automatically is added to the form.
 * Is there a way to correct this?
    By the way, I’m usig classipress theme if that
   is important. I need auto username because of author pages, i don’t want usernames
   in url’s, number’s are better 😀
