Thanks, Juan ... I added this great article - "Learn Chinese online: 36 excellent free resources" ... http://www.saporedicina.com/english/learn-chinese-online-25-excellent-free-resources/ - to the Mandarin (Chinese) World University and School, planned to become an extensive, online MIT OCW-centric online university, and in Mandarin Chinese!
This Mandarin language (Chinese) language, wiki, subject page at WUaS - http://worlduniversity.wikia.com/wiki/Mandarin_language_(Chinese) - will be an online university in Mandarin, paralleling the other United Nations' languages', wiki, subject pages, which will become MIT OCW-centric, WUaS universities, also in those languages:
Arabic language -
English language -
French language -
Mandarin language (Chinese) -
Russian language -
Spanish language -
This article doesn't appear to have any Wu language (Chinese) resources, for which there is already a beginning Wu language (Chinese) World University and School - http://worlduniversity.wikia.com/wiki/Wu_language_(Chinese) - which will also become an extensive online, MIT OCW-centric university.
All these beginning universities are accessible from the main, Languages' wiki page at World University and School - http://worlduniversity.wikia.com/wiki/Languages - each a major, MIT OCW-centric World University and School in the making. See, too, - MIT OCW Translated Courses - http://ocw.mit.edu/courses/translated-courses/.
