Lead Generation Help

Hi

I wonder if anyone has an experience with this.

I am using S2Memeber with pro forms.

Currently there is only one user group wich is setup as a free registration.

All content is open to the public with the exception to a few categories and all nested articles.

—> Added to this we would require the following.
1. Lead generation on accessing of selected posts
2. Lead generation of accessing selected downloads.
This would fall in to both registered and non-registered users.
So each time they try access these pages or downloads they are promoted with a lead generation form.
* Downloads would probably be nested in articles to anything under a certain line needs a lead generation form to be filled.
This is recorded, sent to admin on who viewed what etc.

Our site is running 100% and working like a charm, just need to know if we can use anything within S2 member to do this or any other plugin that can work hand in hand with S2 Member.

Any help would be appreciated.

regards
Stef
