Here's some interesting information. John Robbie died right after he released the info on how to identify Nordics. He said that they have a screwed up finger.

And this article by Montalk is very insightful. He's a very careful and lucid thinker. His style of writing and analysis is nice to have in a field rife with craziness, assumptions, and paranoia.
