For many charities, online fund raising has continued to grow, even during the recession, but the rate of growth has slowed.

Even for organizations that increased the total amount they raised online, the size of average gifts they receive has decreased. What are the reasons for this drop?

Join us on Tuesday April 20, at noon U.S. Eastern time for a live online discussion about the current state of online fund raising—and the results of The Chronicle's annual survey of online fund raising.

The Guest: Madeline Stanionis, the founder and chief executive of the Watershed Company, a San Francisco consulting firm that helps nonprofit organizations with online fund raising, marketing, and other services. Ms. Stanionis is the author of The Mercifully Brief Real World Guide to Raising Thousands (If Not Tens of Thousands) of Dollars With E-Mail.
