Improvements to Navigation:

It is a constant battle as new material gets added to keep things well indexed and findable. The basic system of categories and tags works well and there are several improvements to the presentation. At the foot of every article you will now find the author detail with a contact link, a note of the sources used, a list of the category and the tags for the article which link to lists of all other articles in the category, or all articles with the tag you click on. You will also see any comments that have been added by contributors after publication.
