NEW YORK (AP) — Facebook wants to help you share your organs.

Users in the United States and the U.K. can enroll as organ donors via links to official registries on the world's biggest social networking site, said CEO Mark Zuckerberg. The links should make it easier for people who want to donate their organs to sign up.

Facebook users who are already organ donors can add that information to their profile page, now known as their timeline.

The Facebook-related firings have begun: A teacher’s aide in Michigan was let go from her job after a school administrator demanded that she turn over her Facebook password and she refused. The aide, Kimberly Hester, is preparing for a legal showdown with the school system.

The incident that prompted administrators to ask Hester for her password occurred last spring. According to  local news station WSBT, “She jokingly posted a picture of a co-worker’s pants around her ankles and a pair of shoes, with the caption ‘Thinking of you.’” Hester wasn’t using Facebook during school hours or at a school computer, but her brand of humor got her in hot water at work anyway.

Facebook plans to file documents as early as Wednesday for a highly anticipated IPO that will value the world's largest social network at between $75 billion and $100 billion, the Wall Street Journal cited unidentified sources as saying on Friday.

Facebook's initial public offering is likely to set a new standard for how low investment banks are willing to go on advisory fees to win big business.

The world's largest online social network is expected to tap public markets for $10 billion in the coming months in an offering that will value the company at up to $100 billion, according to sources familiar with the planned IPO.

Later this year, Facebook is expected to IPO at a valuation close to $100 billion.

More than anyone else, the person responsible for that success is Facebook's 27-year-old cofounder and CEO, Mark Zuckerberg.
