Skarpz,
The problem is that should you write and publish a book/movie script about John Titor you need to think it through. What if you decided to write a book about Superman. Would you have second thoughts because someone else just might own the idea (not ot mention the word) about "Superman"? That's the problem. The John Titor Foundation has already copyrighted "John Titor" in 2003. John Titor is a fictional character owned by Boomer, the person(s) behind John Titor. Under most circumstances you cannot write and publish a book about John Titor without the permission of the JTF
even though Boomer didn't write but a scant minimum of the story. People like me wrote the majority of the John Titor Saga through our posts. Hell, about 1/3 of "Titor's posts" were made by Pamela, not Titor.
If you don't believe me then go ahead and do it. The JTF didn't hire an attorney who specializes in movie making and copytight on a whim. Good luck with your endeavor but do be careful. There's already an attorney lurking in the halllways.
