Looking for a hosted solution to raising funds? I just came across http://www.indiegogo.com/. I am going to keep writing on how Magento can build a web site for raising funds, but you should definitely consider whether you can just leverage an existing platform.
How did I come across this particular platform? From Dean Nelson (VP @ eBay, working on making our data centers greener amongst other things). He with his mother are working on getting a school built in Sesawng India. If you look at the site, it does a number of things I have mentioned before, such list a range of dollar values you can support with showing what can be achieved with that funding.
Hey Dean! This does leave me with one question… Where do you get the time and energy for all you are up to!!!
