Unfortunately, they are not translated into another language. It's more about getting browsers to display the pages properly... They are only "mirrors", so that you can see the current English version of the page. If you would like to provide translations for the MediaWiki pages (preloads), let me know and we can work on those (I can only read a little NL, so I don't want to do it myself).

If you want to provide translations for regular pages, you only need to use interlanguage links (which show up at the bottom of pages), for the translated page. The page Strawberry has examples of how this has been done for other languages.
