check to see if any resellers have "All Features (warning: root access)" checked.

[nat]

Long time ago before ACL List I think it could have been possible for me to have accidently checked "All Features" instead of the one above it.

Is there a way I can easily check to see if that feature is enabled. I don't want to go through all of them and look.

It don't seem to be in /var/cpanel/resellers

As long as you don't see
username:all,
in that file, you should be safe.

That's how they're recorded if given root access (all features).
