On top of Your listed translations in CXT, You can add an new translation, and choose languages.
Great news that Google translation services are now available on Wikipedia. Google has a great translation service and I think this will genuinely help translators who use machine translation appropriately and with much brushing up afterwards.
I read in the FAQ for this matter that Google Translation services are not available in the enwiki, which is a shame. Therefore people who wish to use Google on the enwiki can continue to use my GoogleTrans gadget which offers both Google and Yandex translation services(Google default). See for help on the use of GoogleTrans gadget with the Content Translation system.
Thanks for the advices, but my question was what to do to get WMF to add German as a language to the translation service.
Button + New Translation
Use this to translate from German. There, just choose an article and destination language.
No, my question is, what should we do, so that WMF adds German as a target language to the machine translation of the Content Translation.
We follow a gradual process for enabling machine translation support for different languages. Community feedback is very useful in this process, and I captured your request in this ticket. Thanks!
With the improvements brought by the new version of Content Translation and the integration of new translation services, I think we can consider expanding the support for more languages soon to some of the remaining wikis.
