This post clearly outlines how to use the Facebook fundraising page that is available; it does require that you are a 501 (c) (3) and uses GuideStar’s listing as confirmation. It also offers the chance for your donors to opt in to your email list and allow your supporters to fundraise on the market’s behalf.  For some markets, this feature may be the answer to their fundraising needs for now.

As is mentioned in the post, the key to this is to make sure that your GuideStar page is up to date.
