I am glad it was easy to find! I was on Syl Arena's site earlier this morning, looking at older articles, and saw how he recommended setting Speedlites this way. Of course, this allows the batteries to drain if the user forgets to switch the flashgun off at the conclusion of the shoot, but I usually have spare batteries with me, and charge my batteries almost daily.
