The National Coalition for the Homeless has an organizing manual that talks about the more than 3,200 homeless people who died last year without a roof over their heads. You can see what some of last year's participating cities have done and and decide how you can help.
Let me give a shout-out to Bloggers Unite and urge fellow bloggers to get involved. From their website:
Bloggers Unite is a community that cares.Bloggers Unite is an attempt to harness the power of the blogosphere to make the world a better place. By asking bloggers to write about a particular subject on 1 day of the month, a single voice can be joined with thousands to help make a difference; from raising awareness for cancer, to an effort to better education systems or supporting 3rd world countries.
How It All BeganBack in early 2007 Antony Berkman was the CEO of BlogCatalog.com, a social network and blog directory whose mission was to deliver the most amazing collection of bloggers to the type of audience who love and crave new blogs. With BlogCatalog designer Oscar Tijerina and his brother, programmer Daniel Tijerina, Berkman began working on an idea to use the large network of bloggers for a force of good. The idea was simple, the BlogCatalog team would pick a topic and ask bloggers to participate on a single day to raise awareness about a particular cause. Within a week the BlogCatalog team began creating a landing page and organizing the very first Bloggers Unite Challenge.
On July 18th 2007 the Donor Awareness Campaign became the very first attempt at using the blogosphere to collectively spread the word about a topic for the good of mankind. Seven campaigns and a year and a half later bloggersunite.org was launched to help spread the word even further.
Today, BloggersUnite continues to branch out, giving any user the resources to create and manage a campaign of their own no matter how big or small. We believe that no cause should go unnoticed and we strive to help bloggers find new and exciting ways to use the blogosphere for good because together, we CAN make a difference.
