• Please try to fit a new page into the already existing category tree.
• If you have to create a new category, choose the name and place wisely (try to stay close to Wikipedia's categorization scheme).
• Instead of creating a new page and redirect it to another for link aliases, choose piped links instead. See here for more infos about piped links.
• The one and only root category is Category:Contents. All other categories have to point to it (over one or more subcategories).
