Hello and welcome to the forums,
To provide any real help we will need more information.
First, make sure that you familiarize yourself with a short guide on Permission Editor, available here: viewtopic.php?f=8&t=950
Then, on a test installation, try it out and see if you have problems with any particular part. If you do, feel free to post your question here - tell us what exactly you want to achieve and at what point you're getting stuck.
Kind regards,
Arek
