I currently have 23 rep and am aware that I get the "comment everywhere" privilege at rep 50. I can post an answer, but I cannot add a comment to the question.
I would like to use comment to clarify the question with the OP because I might/might not know an answer and I don’t want to post an answer if it is wrong. Getting down votes on answers is not something I want.
Not getting the ability to comment on other people's answers until 50 rep is understandable.
Basically it seems to me that I should be allowed to clarify a question using comment when I get the privilege to answer a question. i.e. Log In
