====The Code====
After sending this form to Massacls the changes where made and a small protocol is shown:

**The sourcecode is the first draft and in an alpha-status. **
**It works, not more, documentation and some changes for translation etc. will following.**

%%(php;1)
<?php
if (isset($_GET['action'])) //we have to show the input form
{
//We show only a form without any data, so no security checks are possible.

//First of all, put all the id_xxx=on into string for easier use
$ids = '';
reset($_GET);
while(list($key,$val)=each($_GET))
if ($val == 'on' && substr($key,0,3) == 'id_')
$ids .= substr($key,3).'|';

//Perhaps it is usefull to use the same as in acls.php
echo $this->FormOpen()
