There have been a few occasions where new users have had the same problem as others, but the issue hasn't been resolved. For example Ben in this Super User question. Unfortunately he has asked if the issue has been resolved as an answer to the question, obviously due to the fact that he doesn't have enough rep to comment.
In my limited experience with Super User thus far, I have come across this situation a few times now. I am wondering if we can grant new users the ability to have a limited ability to comment on other's answers/questions. Maybe only 1 or 5 comments a day/week or something along those lines. This would help to keep answers relevant to the question and not cluttered with "useless" material, but still grant ability to new users to inquire further about questions or answers that they come across.
