NT Society / Scam mail!
Well I too received a letter from the NT Society, offering me to join their secret society for 'Free'. I felt there was something fishy about the entire offer so I tossed the letter aside. I was cleaning today, and I found it, hence i googled it and this site came up.
I was not at all surprised about the scam, however the one thing I found interesting was the two people who mentioned that they visited 'The Secret' website prior to receiving the letter from the NT Society, since I recall doing the same. Few months ago I went to the Secret website as well. If 'The Secret' has got something to do with it they can get in a hell of a lot of trouble for not respecting the privacy laws.
If others have went to The Secret website prior to receiving their scam letter, please let me know.
