On your profile, November 20th is what you listed as your birthday, @Silvia Benoit ; so if that is not your birthday, maybe you can let Ken know what the correct date should be. Otherwise, this date is going to show up every year as your birthday. But, regardless, we all wish you a happy birthday, whenever it is since we have no way of knowing what is the correct date if November 20th is not correct.
Now that I think about it, I used my SIL's birthday here before I got to know the place. I don't let too much personal info fly around the internet. It is close enough so I would not be insulted if you gave me a birthday wish then. Just don't tell me how old I am.
My profile birthday is also "close enough," for the same reasons. It's not because of getting to know members, it's because the rest of the WWW that has access to the info.
