Additional version of Nynorsk (nn)?

I agree of course with you about the lack of ancient greek terminology for some or many computerese parts of the interface. Thus I believe an "ancient greek" localization will have to be incomplete to some extent. As long as there is not a wiki of ancient greek content, this needs no further discussion, we can postpone it, maybe for ever :-)

When it comes to living languages lacking terminology relating to the internet, computers, and their technical and social aspects, my position is different. When I began school, even English was lacking almost all of its current computer related terminology, leave alone all other languages. Even a basic word like "file" was associated with paper, or (US) road traffic only. The term "computer file" simply did not exist. So I think, vernacular languages and others need their time to develop their terminologies. Tasks like localizing software may offer opportunities to contribute to that.

Which brings us back: Developing additional modern terminology for long dead languages actually means reviving them. That happened for example in Israel, giving us modern Hebrew. Imho, such processes need broad support in real life to have a chance of success.
