I want to rewrite a simple ZPublisher banner exchange to a Zope app. I'm new to Zope and I don't know how I could to it. What I need is a way to create user accounts (need not to be Zope users) which different fields. A new user should submit a HTML form with password, name, email, etc. and a ne user account should be created (user object?). The user should be able to modify or delete his user account data.

I'd look at: (a) UserDB, (b) ZSQL Methods, and (c) a Database Adapter (DA) for your favorite, platform-capable database The UserDB will let you create Zope users that are stored in a relational database. ZSQL Methods and your favorite DA (e.g., SybaseDA, ODBCDA, etc.) will give you the connectivity to the rdbms. A lot depends on what you want to do with the user object. --Rob
