Today I encountered this question which asks whether the punctuation of a given sentence is correct.
It is correct, however, I have only added a comment since I consider a statement such as "It is correct" to be too short for an answer.
Question: how to deal with questions whose answer are either 'yes' or 'no'?
I can imagine
writing a comment
or writing an answer and elaborating on the topic
However, the latter can sometimes really be an overkill, for example when the OP actually knows the grammar rules, but he just wants to get confirmed by others.
