I have a Facebook Fan Page and would like to make the wall content only visible to fans. So if a user sees a link to an article on my fan page somewhere and tries to click on the link, it will take him to a page that says something like "To read that article you have to become a fan". Then if a user becomes a fan he'll be taken to the wall, where a link to the article will be.
I believe this is relatively simple and involves creating static HTML iframes. Let me know if you can do this.
