Here. Seems to just be starting up, but they have pages where you can make notes on judges. Which, I'm sure, will require some moderating! On the other hand, notes on such are always useful.
Chuckle--I was at counsel's table when Steve Halbrook argued Printz, and the clerk warned everyone in advance: CJ Rehnquist is experiencing bad back pains, can't sit for an entire argument. Don't be concerned if he suddenly gets up.
It was good to know, because otherwise you'd be most disconcerted when the CJ gets up, as he did, with a grim look (he was hurting pretty bad) and begins pacing back and forth behind the other Justices while the argument is ongoing. It looked uncannily as if you had to hacked off the CJ that he was too angry to speak, and was pacing while he brought himself under control before ordering security to grab you and throw you down the steps.
