Currently our main reason against another language version of our wiki is that our main contributors only speak English (except me, who also speaks Danish), so the real issue have been whether we could keep the high quality of our English version in the other versions.
For this reason, I am not going to ask for translations, I would prefer it if someone would feel for the show as I do, and write about it in their own language.
Translations are good, but to keep really focused, you got to go with the heart.
A German and a French version would not be a terrible bad idea, given how Futurama is very popular in Germany (as well as Austria and Switzerland) and France (as well as Québec and other places) seeing as the show also has German and French versions (See more about foreign versions of the show here
I have noticed there is a German Futurama wiki somewhere on the net, not that that would stop us from creating a German version of our own. I have also noticed that the Russian Wikipedia is pretty well integrated with the show, having articles about every episode.
Dutch wouldn't heard either, as I know several Dutchmen who also likes the show and would probably be willing to contribute.
But yes, we are interested in opening the wiki in other languages, we just need to be sure that there is a firm "base" behind it. So that the version of the wiki doesn't die a few weeks afterwards. Also, I will have to speak with the other admins.
