Pages & namespaces
Article
An article is a page about about a certain topic. An article is always sorted into the namespace "(Main)". Pages in other areas ("Help", "Templates" etc.) are therefore no articles, but (special) pages.
Page
A page is every single page in TangoWiki. Every page has a unique URL. Pages include articles, discussion pages, special pages, template pages, category pages etc.
Namespace
A namespace is a group of pages. More about namespaces in MediaWiki.
Category
Categories are put into the end of the source code of a page and are shown at the end of a page. Categories allow simple sorting and linking of similar pages. When a page is sorted into a category, this category is created and on the category page itself all pages sorted into this category are automatically shown. The category page itself needs to be created like every other page (with text and categories) after this. More about categories. In the special pages there is a list of all categories.
