Considering you speak French, you can contribute, when you can (or want), to what I consider one of the finest works of systematization of Marxism-Leninism: Georges Politzer's Fundamental principles of philosophy. Right now it's absolutely unreadable, and it's full of errors because it was machine-translated. I ended up giving up on this for now because it was too much work for one person, alone, and I was already having too much work with administration of ProleWiki. As soon as you see the contents of the book, you'll realize its importance. You'll also be shocked by the fact that there is not a single English translation of this work, so an English translation is absolutely valuable.
We can organize 5 or 6 comrades to do this work together once we have more French speakers (I myself am not one, but I happen to have a physical copy of the book in Portuguese). What do you think?
