I searched for similar questions on MSE, like this and this, but couldn't figure out my solution. And since I intended to ask whether I can post my questions on MO, so I think I should ask here.

I know MO is about research-related questions, so I always feel reluctant to ask my questions here. However, I've asked several questions about algebraic geometry on MSE but got no answers, for example, this, this and this. Since I am self-learning this topic, I really hope I can get help. So can I ask these questions on MO? Or future questions like these on MO?

Thank you for your help.
