1. Rename computer 2. Add this computer

Question

I've followed the instructions but they haven't worked.

How do I

1.Rename this computer as it would appear in:

a. Ubuntu One Preferences --> Devices; and [next line]

b. https://one.ubuntu.com/account/ --> Devices

2.Your https://one.ubuntu.com/help/tutorial/install-and-setup-ubuntu-one-8/ says

After you sign in to Ubuntu One via your web browser you should see the Add this Computer button.

I am on the unfortunate side of that 'should'. There is no Add this Computer button.
