How do I sign up a friend for a cuefactor account?

To sign up a friend, sign out of your account (by pressing the 'sign out' button in the navigation bar and clicking the link to return to the login page) and register your friend as a new account. You will need to have different usernames, but both can have the same password. Note that if you have checked the 'Save your username and password on this computer' box, you will automatically be taken to last account registered where you had checked the box.
