This is a maintenance category. It is used for maintenance of the Wikipedia project and is not part of the encyclopedia. It contains pages that are not articles, or it groups articles by status rather than content. Do not include this category in content categories.
This template can and should be removed from an article once it has been properly reviewed. That will automatically remove the article from this category. A review can be undertaken by any user other than the article creator. Reviewing an article follows the same basic principles laid out in Wikipedia:New pages patrol#Patrolling new pages. Once you are confident that the article meets Wikipedia's policies on content and style, the tag can be removed. Note in your edit summary that you have done this.
This category has the following 13 subcategories, out of 13 total.
