In addition, Microsoft Kids Passport can help your Web site comply with the Children's Online Privacy Protection Act (COPPA) passed by Congress in November 1998. (COPPA requires that operators of online services or Web sites obtain parental consent prior to the collection, use, disclosure, or display of the personal information of children.)
