Forgive my newbieness but...  replacing portal_registration.py would impact
all CMF sites, right?  Probably not a good idea...  and subclassing it and
sticking the subclass into wherever portal_registration.py is used would be
basically the same thing, right?

If there were some way to modify the portal_registration tool once the CMF
site was created, like the way portal_memberdata properties can be added,
would that be a way to do it?

Is this kind of thing the purpose of the CMFDefault directory?

Can you clarify "Invoking a customizable script might be better"?

also, OT: are there other places to learn about python scripts than:
http://www.zope.org/Wikis/DevSite/Projects/PythonMethods/FrontPage ? Maybe a
how-to?

thanks,
