The Progressive International is organizing the People's Academy:

Guided by the intellectual and practical work of socialist construction in the Global South, we are building a platform to enrich the debates, theories and strategies that underpin our common struggle for a better world.

The Academy, which is completely free, includes one online lecture (in English which will last about one hour) every two weeks plus a very extensive and comprehensive reading list. The reading list usually includes short texts or book chapters which are considered "mandatory" readings for the lecture, plus a list of more articles, longer texts, and books that are relevant to the material. The academy will start in April and continue until the end of the year. The first lecture is next Saturday, 5 April, at 15:00 UTC. Here you can find the reading list for the first week if you want to get a feeling of it.

I am not affiliated with the Progressive International, but I followed a "summer school" they organized last year, which was similar with this academy but shorter and it was a great learning experience. Especially for people who want to go more into theory and Marxism but are daunted by long texts, this could be quite useful. They also have set up a (non-mandatory) telegram groupchat where people can discuss the material and connect with comrades. I thought it would be a good idea to share in this space, to spread the word about it. Feel free to join if you want and share it around!
