var sidebar_align = 'right';
var content_container_margin = parseInt('350px');
var sidebar_width = parseInt('330px');
What does it mean?
What does it mean root-like administrative control?
I'm guessing that they are referring to you having all the same features as if you had full access to everything on the server.
Ditto, I've never heard of that term, but it sounds like root privilages.
And having root-like privileges means a very powerful access to the server where you can do almost anything you want - both make or break it.
Be careful then. Good Luck!
