I have posted the question "Why can't Jehovah's Witnesses donate blood?" and then discussed that they can use blood fractions at http://answers.yahoo.com/question/index;_ylt=AvkB_y7J3l_kS6SdPuo7674jzKIX?qid=20061017004319AAg97HV
I recommend people from here spend some time answering the questions on Yahoo Answers. If you go to the search box and click on the 'advanced' button you can search questions that are not closed and add comments. The keyword Jehovah comes up with new questions almost daily.
There is a person called Achtung that answers almost every question with references from the WTS website. His professional answers make me feel he is from the Bethel writing department. There are very few exJWs answering, but quite a lot of worldly people saying they like JWs but hate being hassled by them, and think of them as a brainwashed sect.
