Wordpress or Joomla member function - HELP!

[MassivePrime]

Does anyone know of a plugin/theme/template that would allow me to create a site with the following features:

1 section of content that is public

1 section of content that is only for registered members and that is hidden until you log in.

A registration page

A sign up form

Joomla has all those features included in its core but if you want greater flexibility over what content you want public and what you want private (requires visitors to sign-up/login to view), you may want to check out this extension.

There are a few Wordpress plugins that cater for what you're after - but again, included in the core is memberships, sign-up/login functions so not really sure exactly what you're after but here are some resources that will likely come in useful for you.
