I'm pretty new to Stack Overflow and it's vote-system, but I've notice a problem for new users.
I don't know if it's by design or a bug or what else.
- someone posts an unclear question.
- I may know the answer, but I'm not sure of the question and I want to ask "questioner" more information about his/her problem BUT I can't comment on his/her question because I haven't that privilege yet.
What can I do?
