At the top of the "Wing warping" page in Wikipedia, you see a tab that says, "Edit this page." That is a wide-open invitation to anyone -- any visitor to Wikipedia (including you) can edit any page. If you have something to say about wing warping that you feel should be on the page, or if you have an external link that you believe would be helpful to other readers who are reading about wing warping, or if you're compelled to write something completely unrelated, then you can add whatever you have to say to the page. Simply click on the "Edit this page" tab and type away.
