Change into passive voice :

, I post question on ELU because I get precious comments, from which I learn.

I post on EF because here I get good answers from experts such as you. I do learn from you. Whenever I get conflicting answers, I follow your answer. You are a great teacher. I learn modern grammar from you. I post here only for this, nothing else. English is my passion, and my sole purpose is learning. Please don't misunderstand me.
