The Wounded Warrior Project is a noble cause as well.  Their URL is http://www.woundedwarriorproject.org.

Also, the Hope Lives Foundation (http://thehopelivesfoundation.org)
is sponsoring a drawing to give away a free house to an Iraq or Afganistan war veteran who has suffered a hardship as a result of their military service.

It's the least we can do for those who have voluntarily sacrificed so much for our freedom.
