If you want the admins to take note, and you have enough interest, you should ask them about it here: Community & Forum Issues - College Confidential
They might not see it otherwise.
As well, there's a dedicated thread stickied in this subforum: http://talk.collegeconfidential.com/...nterviews.html
And usually, the subforums for the selective colleges are active enough that they respond quickly to questions about interviews.
Since interview questions are often seasonal, and may be specific to a school, it might be better to leave the system as-is. That way, the responses can be fine-tuned to the specific college, and may be more numerous since people frequent the college-specific forums to do more than just respond to questions about interviews.
That's just my take on it, though.
