Keiraw, regardless of what it says at the site, it works. And I can tell you that from personal history: I had a designer rip off, almost stick for stick, a stage design I had done some years ago. Were not talking about an adaptation or an hommage but a line for line theft. I hauled his ass into court and sued him for every penny hed made off the project (which was a pretty sizable sum, far more than I received when I got the original commission from a much smaller theater). The one thing that saved me was being able to prove the date of creation, thanks to the US Postal Service and its registered mail. So while it may be "myth" to the bureaucrats in Washington, it holds up quite nicely in the courts.
