So far, I have translated some of the main pages (welcome, structure) into German. Unfortunately there was no obvious link to that translation within the structure of the wiki. While the menu item "List of…" has a link to pages in other languages, the way maka set it up, it specifically points to lists of games, which I find useful, and I didn't want to clutter it with additional links to the translation of the welcome page.
Consequently, I have added a category "Other Languages" to nav:side. (I hope this is no breach of etiquette to make changes to such a prominent parts of a wiki…) I added links to maka's list of the his translations of the games, and one to my German welcome page. I listed the languages in alphabetical order (like the cross-language links in Wikipedia).
I hope this is an acceptable solution.
