Today I faced a poorly written question (from a quite fresh user). However, the intent of the OP was clarified in the comments that followed.
I choose to answer the question, and I proposed an edit when the user confirmed by a comment that I caught his meaning.
What is the best way to teach such a user how to ask question? Is rewriting an acceptable way? Will the OP be notified of this edit?
Beyond fresh user teaching, I am faced with an uneasy ethical concern: is it acceptable to edit a question toward an answer you have provided ?
