|This is a maintenance category. It is used for maintenance of the LNF wiki project and is not part of the database. 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 is a tracking category. It builds and maintains a list of pages primarily for the sake of the list itself. Pages are added to tracking categories through templates.
For a list of the tracking categories that are automatically populated by the wiki software, see Special:TrackingCategories.
