Your welcome....
Perhaps when there is only a single user you can't log out. You can only shutdown or suspend.
By default I thought it would be nice for you to auto log in to Commodore OS as though its a single user OS like the computers of old.
I believe once you add a user multi-user mode kicks in and you will henceforth be prompted to enter a password.
Good luck figuring out how to remove it once you do.
