Yes. There was in fact a vigorous discussion on how much it should be. Salaries are fixed because of external changes in salaries, and this is not. This is fixed by the board based on what it decides is best for the members. There was an increase in 2006 after the election, retroactive to April 1 of that year. That of course was after the election, in any event, but there was an increase given then of $2,500.
On April 17th, 2007. See this statement in context.
