Children under the age of 13 may not participate in any Program and parents or legal guardians may not agree to these Terms on their behalf. If we become aware that a child under 13 has provided or attempted to provide us with personal information, we will use our best efforts to remove the information permanently from our files. If you are under the age of 18 but at least 13 years of age, you may participate in any Program only under the supervision of a parent or legal guardian who agrees to be bound by these Terms. If you are a parent or legal guardian agreeing to these Terms for the benefit of a child between the ages of 13 and 18, be advised that you are fully responsible for his or her participation in any Program, including, without limitation, all legal liability that he or she may incur.
