Note to web designers: don't enforce a minimum width on elements which are hidden on overflow. I had no idea there was a way to sign up or login because the links to them were not visible and there was no scroll bar and thus dmunoz's comment didn't quite make sense.
Edit: Actually, you've got a slightly worse issue... as I resize my browser window, as soon as it reaches ~1000 (1024?) pixels the header jumps and the buttons disappear outright, even though they would fit on the screen just fine. I don't really care what happens to the buttons, but there is no indication elsewhere on the page that one can make an account.
Glad to hear it! As another much more minor note, the header logo on the registration page seems to be shrunken a good 75%. It's not a problem but it does look comically small.
