Chuck Smith (Berlin) sent us this information:
"We launched our Esperanto course [2015.05.28] and by 15 hours
later 5720 persons had started learning Esperanto with our course.
Of course lots of them need an Esperanto keyboard arrangement and
[NZEA] has the most extensive information on that subject, so logically
we linked to you in our forum:
"Please note, that we are not advertising the Duolingo course yet,
because it is still in an early public testing phase, but if you
mention it, please emphasize that it is still being tested so that
people don't expect a perfect course there."
You can check the status of the course at:
http://incubator.duolingo.com/courses/eo/en/status or go to the home page
and choose Esperanto.
