Dissatisfied that the social networking giant did not go far enough in its recent updates, 10 advocacy groups Wednesday submitted an open letter to Facebook CEO Mark Zuckerberg requesting that it make six more changes to its privacy policies.

"We are glad to see that Facebook has taken steps in the past weeks to address some of its outstanding privacy problems," the letter said. "However, we are writing to urge you to continue to demonstrate your commitment to the principle of giving users control over how and with whom they share by taking these additional steps."

Participating groups included the ACLU of Northern California; the Center for Democracy and Technology; the Center for Digital Democracy; Consumer Action; Consumer Watchdog; Electronic Frontier Foundation; Electronic Privacy Information Center; Privacy Activism; Privacy Lives; and the Privacy Rights Clearinghouse.
