Best way for new users with low reputation to clarify unclear question

Question

I joined Super User today after being redirected here from SO. I saw a question that was unclear and thought I could answer it with a little clarification from the poster, but wasn't able to comment on the question because my reputation was too low.

I understand that new users shouldn't be allowed to comment on questions to prevent 'noise' from curious visitors, but shouldn't there be a way to use distinguish users who also have Stack Overflow accounts from absolutely new users? At the very least, questions that have been migrated from SO should allow comments from Super Users who have active SO accounts.

I'm saying this because I was forced to post answer with an ambiguous question. Won't this affect answer quality? Someone please suggest a good way to avoid this problem in future.

There is a mechanism for this in place; it just requires that you have a little bit more reputation on the site you came from. Any user that has 200 reputation on any Stack Exchange site will get an automatic 100 point bonus on any other Stack Exchange site, allowing you to vote and comment right away. As soon as you get to 200 anywhere else, you'll get those privileges over here!
