Hi John,
All the original language forums have now been converted into fully-fledged courses, so that old link is now obsolete.
The new url for the Korean course is http://moodle.org/course/view.php?id=21.
My Korean assitant Neo has already translated the assignment module and is now doing the core moodle.php file, which is a very long one. When he has finished this I am sure the translation pace will pick up again as many of the other modules are smaller than this.
However, after 5 weeks the winter vacation will begin and I don't know whether my student will have a lot of time to devote to this translation project. If there is anyone else who can lend a hand in translating other modules please contact me! I am also working with Peter Fullarton on this project and any others will be welcome.
I hope you join the Korean course and get involved!
Tim.
