give users the option to edit their question within a certain amount of time after posting it
I have asked a couple questions and after I've hit send I've noticed that there were certain aspects of the question that I wanted to clarify on but there is no option to edit them I understand that this may not be possible if the reader has already seen the question and is working on a response but I think allowing users a certain amount of time to edit their questions could be beneficial and could lead to less negative reviews
You could use the messaging /comment section to clarify your question. Advisors recieve the notification that a was message sent immediately. This would be more effective than editing the question especially if the advisor started working on your reading immediately... They may not see or know that the question(s) were edited.
