Wikipedia and other Wikimedia sites have no central editorial board. Contributions are made by a large number of volunteers at their own discretion. Edits are not the responsibility of the Wikimedia Foundation (the organisation that hosts the site) nor of its staff.
If you find some incorrect information, there are a few things you can do. First, you can fix it yourself! Anyone can edit Wikipedia. Just hit the "edit" button on the top right of the page, make the correction, and hit "Save page". If it's an error or omission, please leave a note at the talk page of the article explaining the problem.
