Some enterprising chap, possibly called “Chris Fisher” if the whois record is correct, has registered the domain name nsa.org. He now appears to be selling email accounts on that domain. The accounts are quite pricey too at $142.00 considering that he is only giving 2 Gig of store. Mind you, his FAQ is quite honest.
I tried to get gchq.org, but it has already gone.
Pity.
