Hello,
I dropped some lines about this idea about two months ago. Now, I wrote a
more detailed plan which is available from
http://www.steckenpferde.de/wiki-translations/
and I also made a reference on Meta's "Talk:Proposals for new projects"
page. I'm not calling for a "proposal" as it can be integrated into an
existing project like wikisource. But what can I do to promote this idea
further?
