thanks to kevin and others that answered my questions, but I need some more clarifications:

...

Zope seems very promising (although the learning curve seems steep) but wandering through the documentation I couldn't see if it has (or how easy is to implement) the two features we need most: - something that checks the broken links AND informs the authors periodically

This would probably be a useful thing. If someone has written link checking code in python, it would probably be pretty easy to convert this to an External Method to go through the Zope database and check for broken links. checking the broken links and sendign out emails is the easy part. what I need to know is if Zope assigns (or has a way to enforce an assignment) of pages or bunch of pages to authors. adr
