The servicemix.org website is actually rendered from the wiki contents.
The tool we use is Confluenza which renders the wiki content as static HTML and caches it (in case the wiki is down). So sometimes the servicemix.org is a little behind (like an hour or so). If ever you want to render the latest and greatest page on servicemix.org then append the ?refresh=1 to the URL and it will disable caching.
e.g.
http://servicemix.org?refresh=1
Also when viewing a page on servicemix.org, you can click on the edit link (bottom right of the page) and you can edit the page. Also 2 handy pages to edit are
the left hand navigation bar http://docs.codehaus.org/display/SM/Navigation
and the top right navigation bar http://docs.codehaus.org/display/SM/QuickLinks
