[Zope] what products to use?

[Owen Smith]

Hi all
    I am trying to implement a site which needs the following-
A forum/discussion
a database of members (400+) who can access certain parts of the site
not available to anonymous users
the ability for members to change their details online
the ability for new members to sign up online
which products or methods should I look at using with Zope
anyone running a similar setup?
(I am confused by choice what works whats current etc etc!)
Owen (newbie!)
