Can I give directly to Common Change to support its mission?

Absolutely! 100% of the money group members contribute to their Group Fund goes to fund requests that you participate in and meet needs that are advocated. But Common Change does have an Administrative Fund which people may contribute to over and above their group contributions [or as individual donations]. These operations contributions go toward administrative fees, web-hosting costs, and other operational expenses of the 501c3 non-profit organization.
