Thank you for your contributions to Wikipedia. It appears that you attempted to improve a page's short description. Short descriptions serve a specific purpose on Wikipedia. They are not definitions of an article's topic, and should not simply repeat the information contained in the article's title. Additionally, many articles intentionally have no short description when the article title is considered to be sufficient. If you have further questions, feel free to consult Wikipedia's information page regarding short descriptions, or leave a message on my talk page.

Thanks!
