[Zope] Newbie-question

hi all, I have specific folder name "art" in Zope in which i installed a user folder, and a user with "manager role". now i want anaonymous user to access i.e view the website ubeneath the folder "art". Therefore i granted "View Permission" to the "Anonymous Role" at the folder level "art", but that doesn't work. Then i came to the conclusion to grant that Permission at root level. But that doesn't work too. So my question is: What i have to do if: 1. i want only a manager user acces to the ZMI beneath the folder "art" 2. grant anonymous user acces to view the "generated pages" beneath this folder Thanks in advance Thomas Adams
