One thing I'd like to know is exactly how 'm going to be notified about the RC. I signed up, got the little message saying "You'll be the first to see WinXP, yadda yadda yadda" and also signed up for the newsletter. I never got any kind of "confirm subscription" message for that.
Now, I'm wondering, how am I going to know where to get RC1 when it comes out?
