adding unsourced categories please read wp categorization articles categorization of articles must be verifiable it should be clear from verifiable information in the article why it was placed in each of its categories your recent addition of categories to several articles fails wp verifiability for example nation of islam doesn't mention black power let alone cite a reliable source describing the organization as related to the black power movement so your addition of category black power was inappropriate please follow the categorization guideline in the future thank you c f e b f eb b
