Just a quick update here; I'll add more when I know more.  But since this is the first day of NaNoWriMo (and yes, I will be participating), I thought a caveat might be helpful:
Don't spent all the time at your computer.  It's bad for you.
Yes, thanks, Mom.  I know I need exercise and stuff or I won't be healthy.  But so what?  
No, I mean it's really bad.  As in, "Chronic pain despite All The Ergonomic Things and Gunnar Optik glasses." 
During NaNoWriMo, I'm still getting up every hour and walking around.  And I advise you to do so, too.
Also: good luck and have fun to all of those doing National Novel Writing Month!
