Just started with rasp pi.
I am logging on with 'pi' and 'raspberry'; shutting down with 'sudo' 'halt'.
Am I using a root account by doing this? I understand it's best not to be using a root account for fear of irrevocable damage.
Should I just continue with pi and raspberry log in?
Also, I think I may have created a user account in my name in error. When in some initial confusion I attempted to create an account I've got a message that that name has already been used. Can I see somewhere what accounts exist on my pi and change or delete them if necessary?
