More and more women are making big gifts to charity, but many fund raisers struggle with how to best communicate with women donors.

What can your organization do to more effectively reach female donors and volunteers? What can charities learn from companies that promote products and services to female consumers? And how can this approach help your charity connect with men as well?

Lisa Witter, a marketing expert and author, will answer those and other questions today at noon Eastern time in a live discussion with Chronicle readers.

Ms. Witter is chief operating officer of Fenton Communications, in New York, and co-author of the book The She Spot: Why Women Are the Market for Changing the World — and How to Reach Them.

This discussion is open to everyone, not just Chronicle subscribers. You will have a chance to ask Ms. Witter questions from noon to 1 p.m. A full transcript of the discussion will be available after the discussion.
