         /* Attempt to send the email with new password */
         if($mailer->sendNewPass($subuser,$email,$newpass)){
            /* Email sent, update database */
            $database->updateUserField($subuser, "password", md5($newpass));

	     $_SESSION['regsuccess'] = true;
         header("Location: ".$session->referrer);
		 
		 if($mailer->sendWelcome($user, $email, $pass)){
		 
		 }

  function sendWelcome($user, $email, $pass){
      $from = "From: ".EMAIL_FROM_NAME." <".EMAIL_FROM_ADDR.">";
      $subject = "Elite ticket master - Welcome!";
      $body = $user.",\n\n"
