Yea, I looked that up, and I still don't get it. *dunce*
Nothing to get, really. Someone who knows I speak Arabic and English am not a Muslim anymore etc... thought it would be funny to try and pretend that GCHQ are trying to recruit me to spy on Muslims by sending me this stuff in the post.
The GCHQ CD is a genuine one.
Whoever sent it made a mess of the letter though lol
