# edit file to add new user
This is _not_ how you do this! I stopped reading once I read that line. I can't take anyone serious who does this.

This is now how you edit that file. You should edit this file using `visudo`, which "locks the sudoers file against multiple simultaneous edits, provides basic sanity checks, and checks for parse errors" (quotes text from man page).
1) You should technically only be editing /etc/sudoers through visudo.
2) You should also have an admin/root group. All you would need to do then is "sudo adduser <blah> admin/root". This group is the one you specified in /etc/sudoers to have root permissions.
