Well sourceforge decided to make their filesystem readonly which takes out Dokuwiki (used for this wiki) which stores content in files.
A dump of the content is available here. Note that this is encoded as ISO-8859-1 - if you want to load it into your own Dokuwiki install, you will need to convert it first. See here and here for details.
