Actually, the easiest way to create a secondary journal is by going to your Invite Someone page, then clicking the link at the top to see your complete list of invite codes. You'll then see a list of codes with "Use this code" links next to them. You can just click the link next to the code of your choice to create a new account; you don't need to be logged out first!
You'll still need to log out and in to switch between them once it's already created, but not for the initial creation step.
