How old do you have to be to sign up for Sparkworkz

There is no age restriction to sign up to online games site Sparkworkx.
You can be a one year old and still register yourself under your chosen user name!
You will be asked your date of birth when registering for the first time. Perhaps this is so they can send a birthday message once a year!
Of course, as with any online site, it is always best to get your parents' permission before using.
