The handbook for NGOs prepared for the UN Commission on the Status of Women in New York last month includes an excellent explanation of how the United Nations is structured and operates and how CSW was established.
It also has a section starting at page 20 on digital advocacy for women's organisations that is a great toolkit for BPW clubs. Use it to start a discussion at your club – how can you promote your campaigns through digital platforms and empower women in your locality and your state?
