When I started out on WDWMagic I always referred to my son as DS9 or DS10... It was a clear way to identify him to people and give context of his age without using his given name on an open internet forum. In this day and age it's too easy to slip up and then suddenly you're hearing from the police that your missing son was kidnapped by a stranger who knew his name... :shrug:
Now that he's older and a member here himself, I'm not as concerned about using his given name.
I've never had issue with folks for doing it, but if they don't I'm not going to chastise them for child endangerment eiother. :animwink:
