Although I have absolutely no problem with any of the group knowing anyone's birthdays, it has been allerted on the BBC that this could be an online fraud hazard. I've tried without success to remove my D of B but without sucess. Perhaps the administrator could remove this field for all of us, just to protect our online safety from hackers.
I would agree with Linda on this one. Please remove mine as well. My wife is the head of our towns neighborhood watch and we just had a police presentation on identity theft. They mentioned that date of birth is an important piece of information and to consider were you post that information. Although it is pretty scary how little a thief needs and how much they can get away with.
