Category Uncategorized is a kind of "complement to all other categories", to make uncategorized pages easier to find.
To get a list of all pages tagged as uncategorized, click on the "Category Uncategorized" link at the top of this page.
Pages don't get added to this category automatically, but if you edit a page that does not carry any category link, and can't think of a suitable category for it, then please add a [Category Uncategorized] at the end of it — this will make it easier for people categorizing pages to find it later.
