Can you report someone who has child (blank) (I won't say it) on there computer?Even if the computer's shared?

The National Center for Missing & Exploited Children (www.NCMEC.org or missingkids.com) provides a reporting mechanism for child exploitation (CyberTipline). This non-profit was created by Congress, and partial funding for this agency is provided by the Dept of Justice to coordinate this kind of information and report it to the appropriate law enforcement agency for investigation.
