Join us Tuesday, August 25, at noon U.S. Eastern time for a live online discussion on how people who work outside of the nonprofit world can pursue long-held dreams of starting a charity to attempt to solve many of the world’s most intractable problems. How do you set up a charity? What are the toughest obstacles? And how are these new charities and the people who establish them changing the philanthropic landscape?

The guests will be:

• Connie Duckworth, founder of Arzu, a nonprofit organization in Chicago that helps Afghan women out of poverty by providing a way for them to earn income selling the hand-woven rugs they make. Previously, Ms. Duckworth worked for Goldman Sachs, where she was the first female sales and trading partner, and rose to lead the investment firm’s Chicago office.

• Lisa Endlich, author of several books, including Be The Change, which tells the stories of 11 people who seek to alleviate social ills through the charities they’ve established. Ms. Endlich also wrote Goldman Sachs: The Culture of Success, and Lucent and the Crash of Telecom. Previously, she worked as a management consultant, a political fund raiser, and a trader and vice president at Goldman Sachs, in New York.

The Chronicle’s online discussions are free and open to everyone. People who ask questions in advance have a better chance of getting answers.
