      /* Username error checking */

      $subuser = $_POST['user'];

      $field = "user";  //Use field name for username

      if(!$subuser || strlen($subuser = trim($subuser)) == 0){

         $form->setError($field, "* Username not entered<br>");

      }

      else{

         /* Make sure username is in database */

         $subuser = stripslashes($subuser);

         if(strlen($subuser) < 5 || strlen($subuser) > 30 ||

            !eregi("^([0-9a-z])+$", $subuser) ||

            (!$database->usernameTaken($subuser))){

            $form->setError($field, "* Username does not exist<br>");

         }

      }
