If you want to add your computer to Ubuntu One and somehow the page to add/connect new computer is not there, you may want to try this.
It works for me with Ubuntu 10.04. Open the terminal and type this :

• make sure your Ubuntu One client is installed :
  sudo apt-get install ubuntuone-client-tools
• authorize/add/connect your computer to Ubuntu One:
  u1sync --authorize
  it may take a while to actually open the page, just wait. It will open the sign in page, and then the confirm computer access page, like this :
  
  

I already made free 2GB Ubuntu One account for quite awhile, but only today decided to utilize it.
