I have been touring around the site and I have found oneone of the "resource questions". One thing that I noticed is that as of today, all the resources are in English (except for one which is in Latin and I would like to try it for my kids... I still recall fondly when I read Asterix and Donald Duck in latin, it was real fun).
So I propose that the canonical answers to these questions (I agree with all of them) mention, when relevant, resources in other languages. German or Italian come to mind as two languages which have been used to produce useful resources.
So this is a meta-proposal, in a meta-site :-)
