FirstGiving.com - startup that allows people to create funds for any non-profit venture.

I would also add to that list FirstGiving.com ... they're a Cambridge, MA startup that allows people to create funds for any non-profit venture. They can automatically cut a check to most accredited national (US)/international charities. What makes them unique from from sites like Fundable and ChipIn, besides being able to automate the process of collecting for existing charities, is that they have no cap on fundraising (Fundable and ChipIn cap you at $25k, as far as I know) and they have a $1 minimum donation (most sites have a $5 minimum, likely due to credit card processing fees). I've been considering using their service for a non-profit fund raising project.
