This article was added manually as a standard user for testing purposes; Any user who has signed up and confirmed their e-mail address (via the link emailed to them as a part of the sign up process) can create an article.
Before articles are fully published, an administrator will need to moderate the article and set whatever categories are needed; The user can set the categories, but an administrator will likely remove any references to the special "Featured" categories when they moderate the listing.
Articles are not a part of the main directory; instead they are standard WordPress "Posts". This allows for the full usage of Wordpress' editing features, which is more appropriate than the facilities provided for the directory - While both allow you to add images and rich text, the directory listings enforce a specific structure so that all listings are displayed equally and nobody gets an unfair advantage; this is not needed for articles, so there is less restriction on what can be added.
Articles also have a much simpler search function, as provided by Wordpress, because the extra tag-based search functionality of the listings is not required either. That's why there are two separate pages for a listing or article search.
