Arianna Huffington: In the weeks leading up to the Republican and Democratic conventions, we had countless meetings, conference calls and epic email threads geared toward finding solutions to our country's ongoing jobs crisis. And I'm delighted to announce that today we launch JobRaising, one of the initiatives that grew out of those discussions. Along with the Skoll Foundation, CrowdRise, and knowledge partner McKinsey, JobRaising will help job-creating nonprofits raise money, raise awareness and help put Americans back to work. The Skoll Foundation has committed $250,000 to a challenge that will fund the most creative and innovative ideas from nonprofits working to create jobs. If you're involved with a nonprofit, you can apply here. If you're not, but want to help expand the search for solutions to the jobs crisis, check back to see featured nonprofits that are creating jobs and pledge your support to those whose missions resonate with you.
