UPDATES

I thought it a good idea to create this page so that people who visit the site regularly may be made aware of any additional material that may have been added to a particular page, or indeed the addition of a new page.
With existing pages, only if there has been a significant change to the page and the information it contains or how it is presented will I make reference to it. 
If I have only corrected a found spelling mistake or re-phrased a sentence or two to make its meaning more apparent, then that will not be considered worth an individual mention.
