Jourles,
you most likely have heard of http://www.chillingeffects.org
They maintain a database of companies/organizations who send out those "cease and desist" letters. As far as I know there is no entry of "Watchtower" in their database. You might consider sending them a message with this WT letter attached and request this be put up on their online searchable database for the whole damn world to see.
I'd love to see the Watchtower making company to the Scientologists on the db, and also making some headlines there.
They also have quite a few interesting links on copyright issues.
I read on the other thread you mentioned some people suggesting blacking out some portions of the letters, or maybe even showing just part of them. I, personally, don't like this idea since it takes away what makes them REALLY interesting, namely, the full context and content, proof of its authenticity, allowing the reader make a judgement by what he/she reads and not by what someone else thought would be the point worth exposing.
Whatever you decide please keep the original, unedited ones. I agree with others here who said that, if you don't, someone else will end up hosting them somewhere and the end result will be worst for the WT.
Man, I love those letters and am already missing them. They are truly damning as they show the WT has a lot to hide and a lot to be concerned about.
ADVERTISE. ADVERTISE. ADVERTISE.
Long live the internet!, the truly deliverer of the long-promised power of the information age.
