It does actually work, but it takes some programming knowledge. It will be in the user manual when I finally finish it, and I plan to provide a very, very simply example PHP script it some point to demonstrate how it works. Just haven't gotten that far yet.
As to how it works, the TD basically runs inside of Internet Explorer, so it just tells IE to visit a URL (of your choosing) and it passes to the website the same variable information that is available in Points for Playing formulas. This would allow you to get the gist of a tournament's status, but wouldn't provide details like individual player information. That will have to be in a future version.
