The CP site isn't too bad compared to others I've seen, it's just that it's so slooooowwwwww because of all the bright shiny stuff (mostly Flash movies, I think) cluttering up the splash page, and making the product pages (for me, at least) a bit of an ordeal. If they'd just use still images, the whole thing would have a smaller bandwidth drain and load faster, and most likely load more reliably.

About the login/logout process: yes, this is (after the recent redesign) one of the least obvious and intuitive sites I've ever seen, and in that I include several Japanese sites that needed a while playing around with Babelfish to figure out. It's terrible! 

BTW, I found myself unable to check out last night. Clicked on the green button and got an error message. Anyone else having problems?
