[Zope-PTK] PTK, LoginManager and user maintenance

[Dan L. Pierson]

I just added some stuff to the PTK Wiki at
http://www.zope.org/Products/PTK/ZWiki/RefactoringPTK on PTK
Membership issues.  After reading it, I realized that I should
probably post this possibly controversial comment here as well:

User management screens and methods. The only real reason that PTK
needs special hooks into the UserSource is that UserSources have no
protocol for adding, changing and deleting users. It would be very
helpful if LoginManager would add such a protocol, otherwise products
like PTK have to become intimate with the internals of the
UserSources to implement them, which is exactly what ZPatterns was
supposed to avoid in the first place!
