As user, I rule its use (8)

I believe the answer is:

utiliser

I'm a little stuck... Click here to teach me more about this clue!

'as user' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'i rule its use' is the wordplay.
'use' indicates anagramming the letters (I've seen 'used' mean this).
'i'+'rule'+'its'='iruleits'
'iruleits' anagrammed gives 'UTILISER'.

Can you help me to learn more?

(Another definition for utiliser that I've seen is " User".)

I've seen this clue in the Sydney Morning Herald.
