As is commonly the case with places like these, all the views that you find expressed on here in postings and articles are mine alone and not those of any organisation with which I have any association, through work or otherwise.

With regards to any comments left on the site, I reserve the right to reject any that are inappropriate. Spam checkers are in operation so those comments will be excluded also. Otherwise, whatever is said is the sole responsibility of whoever is leaving the comment.
