Sparked is a great way to volunteer online in your spare time by helping nonprofits meet challenges that they face, based on your interests and skills. This could mean everything from basic graphic design to research to copywriting. For example, if you have experience with social media, you might spend a short while brainstorming for ways to connect with people to help fight cancer. Similarly, download the Give Work iPhone app to help give work to Kenyan refugees and offset costs. It works when companies outsource online tasks to Kenyan refugees (like confirming that certain images are of what they say they are, or picking out spam comments on a blog). Through the app, you can spend a few minutes looking over these apps, performing quality control and training the Kenyan staff, enabling companies to keep outsourcing these tasks to provide work to these refugees.
