Tor has a lot of non-english-speaker users around the world. How can we make this SE site useful for them? Is there a way to make an SE site multilingual?
Currently Stack Exchange does not run non-English or multi-lingual sites except the sites which are about languages like for example German Language & Usage. On those sites it is allowed to ask and answer questions in both English and the language the site is about. For a long time there are several non-English sites waiting in the pre-beta phase to get a localized interface: Stack Overflow in various languages. None of them has started yet. :-(
In fact Jeff Atwood - one of Stack Exchange co-founders wrote:
It is not, nor has it ever been, our goal to be the one place in the world for all programming information in every possible human language.

Since that time a lot has changed and individual sites are mostly managed by their communities. I am not sure how much may Stack Exchange Inc. interfere with decisions made on individual sites but I can imagine that a community can decide to use multiple languages. Probably administrators and more experienced users which are in contact with Stack Exchange Inc. can tell more about what is possible.
