If you genuinely want an answer to this question, would it not be sensible to post the query on the main Pros' board rather than in this obscure backwater to which only about 10% of forum members can reply. Many who have not reached the illustrious heights of being classed as "Professional Auto Puzzlers" nonetheless have interests and niche knowledge.
If, on the other hand you are simply posting a topic for pros and feature writers to chew over then it is logical to post it here.
When I raised this question on the forum feedback board, one of the moderators suggested i contact the individual posters. I did so and received an extremely rude reply from one of them on the lines of "I can post things where I want". Now I have reached 200 points, I am using the same argument to justify taking the opportunity to reopen the question.
