"With a title that begins with "Director"?"

Back on Groklaw when PJ first stated her title of 'Director of Legal Research', I posted (anoymously) asking whether the title of Director meant that she was an officer of the company.  (In my country that title would imply that she was, and that she would be on the board, instrumental in setting strategy and being legally liable).  A discussion ensued on GL about the meaning of the word 'Director' in job titles in the US.   PJ responded to my question by stating clearly that she was not an officer of the company.  I don't know if that discussion has been deleted but searching for 'company officer' might throw up the comments if they are still there (yes I'm paranoid, I haven't moseyed on over there to check).
