Thank you for a very good reminder on how to prepare an article.

May I also suggest that anybody replying to articles which have obviously taken considerable time and effort to compose respect the author by doing the same, and construct an equally considered and spell-checked response! Although forum pages such as these make knee-jerk replies easy to publish, remember that your name and that unstructured stream of consciousness you are about to submit will be immortalised.

Off-line preparation is absolutely essential, (as I keep reminding my teenagers who believe they can construct essays from scratch at the keyboard). But that topic is for another forum.

One other point, without sounding like a miserable git: do one-liners contribute anything to a forum? If you've nothing constructive to add - and the mechanism exists - just rate the article.

(BTW, this reply took me about half an hour to compose)
