<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">operators</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for users that I've seen before include "People who take drugs" , "Operators" , "Drug takers" , "subscribers" , "People with a drug habit" .)
