[Zope] User profiles

Is there a product for maintaining/building user profile pages or is this something too trivially implemented to be done up as a product? What I need is a page that each user will have as a start page when they login, that will show them a personal calendar of upcoming deadlines, it will also have a record of their email address which will be referenced by other processes, and would allow them to change their password and such like. hmmm...come to think of it, it does sound fairly straightforward to do, now that I think about it.... Any thoughts, hints or suggestions? bkd
