If a Facebook user posts a worrying status, that person's friends can now report the post and try to get them help.
Facebook will then give them the option to contact the friend, contact another friend for support, or contact a suicide hotline.
The new feature began yesterday.
The social network teamed up with a number of suicide prevention organizations and research centers in hopes of helping people online prevent their friends from committing suicide.
These organizations include National Suicide Prevention Lifeline, Now Matters Now, Save.org, and Forefront: Innovations in Suicide Prevention from the School of Social Work at Washington University.
