Yup....same issues here.  I was up at 5 a.m. with my schedule and tea in hand.  I've been trying every 15 minutes to book something.  I called in at 7 a.m. (waited 25 minutes) and she said the system was down.  So, it's kind of strange that some people could get in and others are still waiting.  I wonder if they have some kind of feature built into the system that only allows so many people at a time to be able to get in?  It wouldn't surprise me.  So here I sit...now 4 1/2 hour later still trying!  I'll let you all know when I can get in.  Any updates appreciated!
