If you found "w3.org" in the source of a page and are looking for the owner
Often people look in the source code of a web page for clues about who owns or created the page. Many pages on the web include mention of W3C; see our FAQ for an explanation. However, W3C did not create these pages unless they are on w3.org. Furthermore, W3C cannot help you find who owns or created these pages.
If you encounter a technical problem using the W3C site
If you have technical problems with our site, please write to sysreq@w3.org with a precise description.
