I was signing on to the Forum today and inadvertently clicked the "register" button rather than the "log on" button.
I immediately say the following:
To continue with the registration procedure please tell us when you were born.
Before 27 Feb 2001 :: On or after 27 Feb 2001
I don't remember this when I registered, though that was a long time ago and I may have just forgotten. But I was wondering why it matters if the person registering is younger or older than thirteen? Does this have a legal purpose? I'm just noting that thirteen seems to be an odd age to ask about.
