A. Your best bet for this sort of information is to check the school specific threads. No one is going to compile it all for you.
B. I'd check all the sites on a regular basis regardless. Maybe they sent you snail-mail and you didn't get it or something.
Most schools have some type of regular meeting time to decide which candidates to invite for the next round of interviews. See if you can find out when those times are (alot of them are published on the same website that you'd have to check for status updates), and then only check it then.
