[Zope] Quick Permissions Question

Zopistas, Just a quick question here - the Owner role; does it inherit permissions from Manager, Anonymous or nobody? The problem is this: I want to give the users of my site limited permissions in their own directory, they should only be able to do a select few things. Is the Owner role the preferred way of doing this, or is it better to create a new role with just a few permissions? In other words, can I limit what the Owner can do in his own folder, or does he automatically have Manager-like permissions in his own folder? A pretty basic question, but I couldn't find a straight answer, and I don't want to make any security holes in the site. Thanks in advance. Alexander Limi http://mp3.no
