I've generally ignored the $20 a month membership option for additional info there, thinking that one way or another I could find what I want for free. That may be true, but it takes a long time.
I just ponied up the $20 for a month and, goodness gracious, it was worth it. Want to know who's representing who and what the email is? I don't know of a faster way to get it. I was amazed. And membership is month by month, so you don't have to keep paying once your need is past.
