e.g. I want to discuss if competency should be translated as προσόν or επάρκεια.
YMMV, but me, I use a forum in the French Moodle course on Moodle.org for such discussions. It has proven to be a good way to do it.
See here to get an idea (obviously in French ): https://moodle.org/mod/forum/view.php?id=1683.
I agree with Nicolas. I've seen they do the same in the German and Russian forums and it is good for the community.
Thanks Stam for your post, and sorry for my delay in responding. I have emailed you about having a Greek Moodle course on moodle.org.
