I gotta go back and find out when 19 was first mentioned on TM... I'm watching the masses on the other threads trying to piece the idea together. ;-)
Good luck :-) If I can help you search let me know where you want me to start.

Couple of chapter 19's with jihad references.
I know for sure that it was way before thread #19.
Thread 19 went up on last year's 9/11 anniversary and we discussed how strange it was that it was #19.
