qa: comment question

Feature

comment question

Description

You should be able to comment on the question, to e.g. ask for more details allowing to answer the question properly

Use Case

see StackOverflow, it is used quite often to make question understood better

Budget

This is a great feature! Could help us as well. I think that both the question and the answer should have an option to add a sentence of maximum 200 characters (like in Stackoverflow)
