Hello, thank you for the welcome. If you get this message, can you please explain to me why I have earned a badge for adding a page to a category when all I did, intentionally anyway, was answer a question? Your help would be greatly appreciated.
The wiki has it set so that when a user answers an unanswered question, it automatically adds the category "Answered Questions" and removes "Unanswered Questions". You were likely the first contributor to touch that page, so it credited you with that category ^^
