Links are funny like that sometimes. I will search Google news for horse racing stories for the home page (
www.paceadvantage.com), and whenever I click on a New York Times story from the Google page, I can read it WITHOUT having to register.
However, if I copy that same exact link to my home page, and then click on it from the home page, I am asked to register....probably has something to do with the referring page being non-Google....
