Can Forums, eNewsletter, Slide In, and Contact Widget be used with Protected Content to direct all i

I am building a new website that has as an important function the collection of names and email addresses into an eNewsletter mail list.

The site will also have several forums on it.

I want to use contact Widget as an overt request for the info., along with Slide In doing the same.

A banner in the sidebar will link to a newsletter signup page.

I want to use Protected Content (or some other plugin if Protected Content is not appropriate) to deny access to the forums until a visitor “pays” with his name and email address.

All collected names and email addresses need to go to the eNewsletter list. If they also go to the site user list that is a plus, but not necessary.

Will all of this work together, and if so, how?
