I will like to add that it is a matter of basic courtesy for someone posting a question to insure that:

(i)  anyone answering it will not have to go into avoidable trouble of re-reformulating it using proper Mathematica syntax, guess missing data etc., etc.

(ii) the reasons for asking a question, be it research, commercial work or homework assignments etc. are clearly explained.

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.
