Does anyone have any idea if there are online courses run by and for communists, to help acquire a better understanding of theory and practice?
I was thinking that if not, maybe a Moodle instance where people can try things out would be good.
Possibly harebrained: it might be better to just add to Prolewiki when we can.
Tsinghua University offers some free online courses that might interest you. Here are a few:
SWCC: https://www.edx.org/course/introduction-to-the-theoretical-system-of-socialis
MZT: https://www.edx.org/course/introduction-to-mao-zedong-thought
XJT: https://www.edx.org/course/xi-jinpings-thought-on-socialism-with-chinese-char
Hopefully these are the kinds of things you’re looking for.
