Just FWIW, here is a dirty little secret. If you own NFA firearms that are registered and legal under federal and state/local law, BATFE .... doesn't give a damn! They don't come to your home ten times a day (or even once in 35 years in my case), they don't follow you around, they don't trail you to the firing range. If you are obeying the law, they just don't care.
As for NSA or anyone else secretly monitoring this site, why do they need to do it secretly or use antennas at "Ft. Mead" or anywhere else. They can just sign on and they are welcome to participate. Maybe BATFE tech branch folks could answer some of the questions people raise; at least they might make sense, which is more than some of our posters do (love 'em anyway!).
No, I don't trust the gum-mint much, but why is it surprising that the White House might keep info posted on its own web sites and e-mails addressed to it? They probably keep copies of letters sent to the WH also. What would the writers expect? If you send me a letter I am free to do what I want with it; the government has the same right.
