The thing is, I'm a complete newbie. I know the rules, but the last game I played was a very long time ago, and even then I was pretty bad. In SC2 terms I'm just a silver who knows the first few steps of a basic build order and has horrible mechanics.
That's why I'm asking you all this question: where should I start, and how do I proceed from there?.
I don't think I can find any practice partners in real life, so it will be 100% online practice.
