Facebook, in an , said the new privacy education effort helps users understand how sharing works on the site and how they can control how they share information. The site received guidance from the Irish Data Protection Commissioner's Office on the new educational effort, the company said.

New users should start seeing the enhanced privacy campaign Friday, Facebook said.

"At Facebook, we're committed to making sure people understand how to control what they share and with whom," Erin Egan, Facebook's chief privacy officer, said in the announcement.

The expanded privacy campaign will include information about how users select an audience for information shared on their Facebook timelines, about how they interact with applications, games and other websites, how ads work on the site, and how to tag people, Facebook said.

Facebook has also added privacy controls so that new users can select audiences for their information about their high schools, colleges and employers, Facebook said.
