Are my administrator privileges restricted?

I am the only person who administrates this site.
Just checked my privileges and I am not sure they are right.
I seem to be able to do everything but just wondering if I should ‘allow’ more stuff.
There is stuff there that says ‘no access’ but I can actually do it.

Then you’re most likely the root (main) administrator and have more privileges. The “Administrator” user group is designed for assigning to the accounts of your staff, which might need limited access to some things.

Thanks ikoshkin,
That explains why I could do all the stuff that was ‘not allowed’…lol
