I Tried to add the site www.sytm.net in the Webmaster Center, but I couldn't. The page said me "The site address isn't valid." My website sitemap: http://www.sytm.net/sitemap.xml

After checking the issue, it seems this is a general Webmaster related issue. As this forum focuses on Windows SteadyState specific issues, this inquiry would best be posted to Webmaster forum: http://social.microsoft.com/Forums/en-US/webmastertools/threads The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction with us. Thank you for your understanding. Sean Zhu - MSFT
