This document discusses using social media for fundraising and information sharing by charities. It provides tips and examples from the Beating Bowel Cancer charity's social media use, including being informal, engaging, and going beyond just sharing information to actively participating in conversations. Case studies are presented on measuring social media impact from a running event. Key recommendations are to sort out social media measurement metrics, focus on telling compelling stories, and let others do the sharing. The "magic three" of social media, email, and websites are discussed as complementary channels to drive different types of actions.
