Online FAQ?

Btw, a lot of the online reference material on XWiki seems to have suddenly gone missing. For example, the document http://www.xwiki.com/xwiki/bin/view/Doc/UserInterface links to http://www.xwiki.com/xwiki/bin/view/Doc/HowToCreateASkin and http://www.xwiki.com/xwiki/bin/view/Doc/WhatIsASpace, but both of these pages are blank. The page http://www.xwiki.com/xwiki/bin/view/Doc/XWikiSkins is almost blank, and I could swear it was not like that last week. And the same goes for the FAQ list itself, which used to be available at http://www.xwiki.com/xwiki/bin/view/Doc/WebHome. Is something wrong with the server? Or have these resources been moved?
