How do I find articles?

The easiest way is to use the search and see what you come up with. There may be a list of categories on the home page which links to lists of articles on particular topics, but only if someone has created one. Unlike most websites, a wiki does not necessarily have a hierarchical structure that all the content is organised into, so you won't necessarily be able to drill down through topics and subtopics to find an individual article. When someone writes a new article, they don't have to put it in any particular 'place' or category. Because of this, many articles aren't actually linked to from anywhere and the only way to find them is to search. Also, the content is not guaranteed to be exhaustive. Unless someone has written an article about your topic of interest, you won't find anything. The solution is to write it yourself when you've found the information elsewhere. Then the next person to search for that topic will be able to find your article. That's what a wiki is all about.
