Hi I installed Zope-PTK from the file http://www.zope.org/Products/PTK/ZopePTK-0.8.2-complete.tar.gz on an Zope-2.2.0-linux2-x86 (SuSE 6.4) - System. I created some Members and realized that those (on a restarted Browser) are able to access the portal-configuration and even change settings there. If you need more infomations, please contact me.
