I was going to wait to upgrade but said wtf and did the online upgrade. I figured I would go pick up a boxed WOTLK later. Then I tried logging in and went ooops. I have to install before I can play. So I started downloading the online version. I guess I kind of thought it would save the install package to disk but it is downloading files then installing them (even before the whole thing is downloaded). Kind of weird.

I can't tell where it is actually installing to. Does anyone know? I'm on Windows XP. Also, I want to copy the new install to my other Wow folders. Do I need to make new folders? And then can I copy my WTF and Interface/addons folders directly into those?
