On Sept. 11, 2001, terror attacks on New York, Washington, D.C. and Pennsylvania killed almost 3,000 people. The survivors, families of the victims, and first-responders found their lives irrevocably altered -- as did all Americans.
Ten years later, the Yahoo! Contributor Network is asking you: How have you changed?
Perhaps you lost someone close to you. Or the attacks compelled you to join the military or volunteer more of your time. Or, perhaps more simply, you hold your loved ones closer to you than ever before.
In honor of the victims, survivors and heroes of 9/11, we want you to share your stories and memories of that day; tell us how 9/11 changed you.
Your story will be featured alongside thousands of others on Yahoo! News' 9/11 anniversary site.
