Oh, my half-joke went too far. While what I’ve written is true, I’m a programmer, and if really needed I can either afford paying for it or write it myself.
I think it would be a waste of money right now, because our study group is tiny and not overly active despite my effort to engage other students. And I’m still figuring out how to use discourse, so maybe I will find a better way. Or maybe I could find some time later to write it myself indeed, it would be a fun weekend project.
