Those twelve and under are covered by COPPA; those thirteen and over aren't. The law itself says "under 13", which is equivalent to "12 or under"; think "pre-teen". If 2007/12/3 is your son's thirteenth birthday*, then we look forward to accepting his submission on that date. If its his twelfth birthday, he still has a year to go^H^Hpractice. - ZM
*COPPA, being U.S. law, counts age U.S. style: you're not thirteen until you've spent a full, completed thirteen years alive. One's "thirteenth birthday" would be the day that becomes the case, despite it actually being one's fourteenth birthday if the actual date of birth is counted. (I guess that would be the zeroeth birthday...) In some other countries, it's customary to give the year in progress as the current age - "I'm fourteen" meaning "I'm in my fourteenth year" equalling "I've been alive a full thirteen years" - hence the distinction.
