[Zope] User management -- Was: Unenlightened XUF question

Why are you looking to use XUF?

I'd go for a normal user folder with a cookie crumbler in the case you've described so far...

OK, I'll back up and describe my case: 1.) authentication allows access to premium content area; no user creation of documents 2.) planning for 1,000-2,000 users (members) within a year 3.) need to store users' email addresses and membership expiry dates 4.) member autonomy to change/retrieve password that's about it :-) It seems natural to store user properties close to the authentication tool, and XUF is pretty new and cool. Which user management product would best do the job? TIA to all, Ken
