your user would belong to the user group by default i believe. Didn't you have to create a regular user during the install? Maybe you already have a user by that name who knows. Regardless, running as a regular user, you'll still have to su to move any files outside of your /home dir. I wouldn't advise running as root simply b/c one mistake can be a big problem. look at the users you have and open /home and see if there are any directories in there.
What do you expect to see at the terminal?
That will show you all dir in the /home dir
