note: Select the proper categories given in Category:Template categories instead. By default, templates used primarily in article space would just fill up a set aside subcategory for that purpose (i.e. any "category:article namespace templates") analogous to the below subcats. Hence, not burdening the system with such useless listing has been the road traveled.
Categories of templates grouped by namespace are listed here. Do not add templates directly to this category; use an appropriate subcategory.
