ALBANY, New York (AP) - MySpace reached an agreement with legal authorities in 49 states on changing its social networking website to help prevent sexual predators and others from misusing it, state officials said yesterday.

Several states' attorneys general said in a statement that Myspace will add several protections and participate in a working group to develop new technologies, including a way to verify the ages of users. Other social networking sites will be invited to participate.

MySpace, which is owned by Rupert Murdoch's News Corp., also will accept independent monitoring and changes the structure of its site.

The agreement was announced in Manhattan by attorneys general from New Jersey, North Carolina, Connecticut, Pennsylvania, Ohio and New York.

"The Internet can be a dangerous place for children and young adults, with sexual predators surfing social networking sites in search of potential victims and cyber bullies sending threatening and anonymous messages," said New Jersey Attorney General Anne Milgram.

"We thank the attorneys general for a thoughtful and constructive conversation on Internet safety," MySpace Chief Security Officer Hemanshu Nigam said in a written statement.

Among other measures, MySpace agreed to:

- Allow parents to submit children's e-mail addresses to MySpace to prevent anyone from misusing the addresses to set up profiles.

- Make the default setting "private" for 16 and 17-year-old users.

- Respond within 72 hours to complaints about inappropriate content and devote more staff and resources to classify photographs and discussion groups.

- Strengthen software to find underage users.

- Create a high school section for users under 18-years-old.
