I wan't you give a great compliment. We use xwiki at our company elitepartner.de and we are very satisfied with it. Also i build my Website on top off xwiki http://www.webtopproject.de. It is used like a cms system. In moment there is no wiki usage on site. In near feature i wan't to activate it on a special space called wiki. To customize the skin is very hard i find, becaue of so many css files. I hope this will be more easy in future releases. Thanks Michael Meierhoff
