sudoers mistake

[Michael Havens]

What do I run? I run an ubuntu derivative, Mint.
I only created one account on this computer (if I remember right).
this is a home used system. I only have one computer I can do this with so
I am stuck with testing on it.
I don't think root's account has been locked in mint as I can 'su root'
<password> and I am super user. Am I assuming correctly?
