Hello, and thank you for your contributions to the Harry Potter Wiki! I just wanted to give you a word on categories: if an article is in a category (say "1881 births" for instance), it does not also need to be in the "1880s births" or "19th century births" category (since the "19th century births" category is in the "1880s births" category, and that one is in the "1881 births" one... it's implied -- everyone born in 1881 was, by definition, born in the 1880s and the 19th century).
Still, thank you for your edits! Keep up the good work! -- 01:04, June 16, 2012 (UTC)
