Hi Eduan,
Sure thing. At this time all I wanted was a way of stopping non-members from accessing the content, so I set up s2 according to the minimum requirements.
Then I blocked all users below level 2 from accessing the private content in the s2 admin.
Next I set the same page that contains the thumbnails (links) to the protected content as a registration page before drawing a widget block and inserting the login with Ajax widget into it.
The nice thing about Headway is that you can easily filter content from different posts all on one page.
Now if anyone clicks a link on the page to try and access the protected content, nothing happens (or rather the page just scrolls to the top if not already there).
To access the content they must sign in, and using the login with ajax widget means the content becomes accessible without reloading the whole page again.
