css and links on xwiki.com

Hi, just a question about css: does xwiki generate some different css styles to make difference between internal and external links?(like jspwiki and mediawiki) is there any hints to use them on the xwiki.com <http://xwiki.com> platform? (our wiki, http://jguard.xwiki.com is hosted on it => thanks to the xwiki team!!). => internal and external links are displayed in the same look and feel. cheers, Charles. ps: it seems you have rolled back to an old version of xwiki on xwiki.com<http://xwiki.com>=> the proxy issue comes back: when i want to edit a page, it displays always the same edit page....
