The Seattle Times reports that the opt-out feature in an online student directory at the University of Washington has ended up causing the very sort of confusion it was supposed to avert. The school has two students named Nate Robinson. One is a basketball star and the other is a cartoonist. The basketball star isn’t in the directory, but the cartoonist is. As a result, the cartoonist’s eMail box is being flooded by people eager to contact the basketball star.
