I compared the ancient version with the current version and the file "include/contact.inc.php" has been changed.

Ancient version, line 236 - 293:

   if(empty($errors))
    {
     $smarty->config_load($settings['language_file'],'emails');
     $lang = $smarty->get_config_vars();

     $ip = $_SERVER["REMOTE_ADDR"];
 
     if(isset($_SESSION[$settings['session_prefix'].'user_name'])) $emailbody = str_replace("[user]", stripslashes($_SESSION[$settings['session_prefix'].'user_name']), $lang['contact_email_txt_user']);
     else $emailbody = $lang['contact_email_txt'];
     $emailbody = str_replace("[message]", stripslashes($text), $emailbody);
     $emailbody = str_replace("[forum_address]", $settings['forum_address'], $emailbody);

      }
     else
      {
       if(!@mail($recipient_email, stripslashes($subject), $emailbody, $header)) $errors[] = 'error_mailserver';

    }
 

Current version, line 275 - 299:

     $smarty->configLoad($settings['language_file'], 'emails');

     $emailbody = str_replace("[message]", $text, $emailbody);
     $emailbody = str_replace("[forum_address]", $settings['forum_address'], $emailbody);
     if(!my_mail($recipient_email, $subject, $emailbody, $sender_email)) $errors[] = 'mail_error';
    }
   if(isset($errors))
    {
     $_SESSION[$settings['session_prefix'].'formtime'] = TIMESTAMP - 7; // 7 seconds credit (form already sent)

In the ancient version, the PHP function mail() is called twice, both for $recipient_email and $sender_email. In the current version, my_mail() is only called once, for $recipient_email.

It would be great if MyLittleForum would send a copy of the email to the sender as well.

If this for some reason is not desirable, then a setting would allow the forum owner to choose whenether or not to use it. Or, it could be an option for the user that sends the email. A checkbox in the form. If the user check the checkbox, he will receive a copy. If he doesn't check the checkbox, he will not.

Best regards,
