Hey Conan, I saw you deleted some categories like Categoría:Novena Generación and other generation-related ones. However, that just deletes the category page itself--the individual pages like Suzuki Kanon will still have it listed as a category, since that information is saved on each page itself. If you'd like, when there are some you really want wiped out you can tell me which, since that's one of the things I use Robo Kiss and the bot tools for--it's pretty easy to tell it to get all the pages in a category and remove that category listing.
Oh yes, there are some categories that I want to delete. The categories Primera Generacion, Segunda Generacion, Tercera Generacion, Cuarta Generacion, Novena Generación, Décima Generación, Undécima Generación and Country Musume :)
