[Zope3-dev] Store information to principals

[Florian Lindner]

Hello,
I want to store further information to principals, like email or homepage.
How can I achieve this in the best way?
Can it be done through a web interface? What is the PrincipalAnnotation 
Utility doing?
Or do I need to create a new principal object? (subclass of 
zope.app.services.pluggableauth.SimplePrincipal?)
At a later point a principal should be able to create user groups (groups of 
other principals). How would you do that?

I'm not expecting complete implementations here (altough I'd be happy about 
it) but I need some information to start (like what Interfaces to subclass 
and implement).
Thanks,
Florian
