Yeah, I just saw that come up on a google search. Surprised that a member page for TP.net shows up (and on the first page of results at that). They may take steps to correct that apparent oversight in the near future.
It appears that the "free" article (Wawrink's Backhand) that you posted is actually in the Members section rather than the Public section. I don't believe that Yandell had intended this article to be available to the public. Curious how you even found the article. I suspect that Yandell would want this link removed.
