Holy smokes-all this time my profile was showing me as a guy. Not that there's anything wrong with being a male-I'm rather fond of some males-but I'm female.
So if by chance, anyone checked my profile and noticed that the gender was male, it was very, very wrong.
Actually, I think the default should be set to "female," not just because the vast majority of us are female, but because fetuses all start out as genetically female, and at a certain point, some change to male.
