I came across this on Friday via one of my feeds (I can't remember which one to give credit to). It's a group in the US who wants 9/11 to become a national day of service. From their website:
One Day's Pay: We're the national nonprofit working to establish 9/11 as a National Day of Voluntary Service, Charity and Compassion. This 9/11, take time out of your day to help a friend in need, give blood, donate to a charity, volunteer your time, or just be kind to others. That's all you need to do to participate.
It's a great idea. Their site cross-lists some Canadian resources (e.g. Goodwill, under "Give away property") Help to channel energy into a postive result.
