Thank you AI1000!
So when ubuntu calls a user "Administrator" they don't mean the "root" user? I only ask this because I'm listed as "Administrator" in the "User Accounts" window.
When I pulled up a terminal to use "sudo useradd guest", it had the following helpful info at the top:
"To run a command as administrator (user "root"), use "sudo <command>".
See "man sudo_root" for details."
Does this mean the "Administrator" only has "root" user powers when using "sudo" commands? Heh, does that cancel out my first question? Thank you if you can answer as its going to take me FOREVER to read and understand the sudo man pages! So scared of that "sudo"!
But it kinda sounds like that command invokes root privileges.
I have SO MUCH reading to do...
I have managed to figure out a small part of my original set of questions:
-Adding a "Standard" user was easy and Ubuntu created it automatically so that I can switch between users by clicking the power icon in the top right corner of the screen. I feel like users have a more complicated system on the windows setup at work, so this is dazzling to me.
Also, I discovered that the "Automatic Login" box means Ubuntu automatically fills in my password for that user. Definitely not what I want! I think will definitely be reading some newbie stuff about encryption and firewalls because even though this is technically linux, I'm NOT using this in a secure manner. Any suggestions on this topic would be appreciated.
