Hi Max, Your mail is very interesting for me, but I think I have missed something (I don't have experience with big sites and I'm reading your -i think- minimal product howto... so excuse me if I am trivial). In my opinion in Zope approach the structure of the site isn't so important, objects have properties and properties permit several (logical) views of the site and this is Zope's strength. For example (I'm only trying to explain my point of view), a teacher's document can have an author-name property, an author-role property, a course property, a topic property..., so it isn't important if the teacher changes school or work... (For several months I have used Zope only because it makes rapid to do simple work with rdbms, but now I think that Zope power is in ZODB). So I think Zope changes the problem from 'site structure' to 'find correct properties'. Can you tell me where I'm wrong? Thank you. Michele
