Join the Chronicle tomorrow when the marketing expert Seth Godin will take questions online about techniques nonprofit groups can use to more effectively spread their messages to supporters.

Mr. Godin will take questions beginning at noon Eastern time.

Fund raisers will also want to join our conversation Thursday, when Chronicle readers will have a chance to ask Brian A. Gallagher, head of United Way of America, about his organization’s new 10-year strategic plan.

The plan, which was announced last week, could significantly change how local United Ways provide money to nonprofit groups.

The one-hour discussion with Mr. Gallagher begins at 11 a.m. on Thursday.

These discussions are open to everyone, not just Chronicle subscribers.

People who ask questions in advance have a better chance of receiving answers during the online discussions.
