At idealist.org, not only can you find potential volunteer opportunities but you can also be a part of a volunteer community.
Go to http://www.idealist.org and click on Find. You will then be able to discover the volunteer opportunities that are available to you. You will also be able to find and connect with other volunteers who share your interests.
Another feature at idealist.org is the ability to have emails sent to you when a new listing is added to their website that you might be interested in. I continually use this very useful feature for myself and others I help. Click on Email alerts at the top of the webpage and follow the instructions.
