I know, I know, Big Al, when the building is burning end to end and people are hanging out of the windows (as used to happen in your day before Post War Building Studies fixed things), you just had to squirt the water first and ask pertinent questions later. However, if one sets oneself up as a free advice bureau, altruistically to work out other consultants' problems for them, so that they can earn more in this time of recession (though in an earlier posting, you did-admirably in my opinion- acknowledge that it is not entirely altruistic and that you do it as a form of advertising your extensive knowledge), one should really take the time and trouble to ensure the advice that they are selling onward is actually right.
This is why I rarely bother, as I have never intended firenet to be my shop window, and I can't be bothered to take the great care and trouble that would be necessary properly to answer very specific queries on premises with which I am not familiar, such as to avoid liability for everyone involved.
However, each to their own. I will of course continue to try to save you from yourself, as a mark of respect for your advancing years, and will try to help those who deserve it (such as my good chums in the fire and rescue services) when they need help with understanding background and philosophy of requirements and recommendations, as opposed to doing their job for them and getting it half cocked.
