Category:Skaro

Please do not put this category in categories with the syntax, category:Planets visited by the Second Doctor, as it creates undesirable recursion in the category tree. On most occasions, it's more appropriate to place the page Skaro in a category, not the category. When one carefully considers where the entire content of category:Skaro (including all its subcategories) goes, the only current category that fits is category:planets.
