The usual response to such questions is along the lines of my original reply. What do you think we should do with such questions, AES - simply reply regardless? David Park has given a solution, so I guess there is nothing more to be said. David Bailey http://www.dbaileyconsultancy.co.uk

Nowadays I usually ignore questions that do not satisfy these conditions. I wish more people adopted a similar policy - answering certain kinds of questions may actually be doing more harm than good. In other words, I think in this case David Bailey did exactly the right thing and has no need at all to apologise. Andrzej Kozlowski |
