Many nonprofit leaders recognize the potential of online social-networking sites like Facebook and Twitter to help build more meaningful relationships with donors, volunteers, and supporters.

But in many cases, they are not sure how to take advantage of these networks — or even how to establish a presence.

The Chronicle on Tuesday gathered several marketing and social-media experts for a live online discussion to help nonprofit leaders get a better handle on those tools.

The discussion featured Danielle Brigida, the National Wildlife Federation’s social-media outreach coordinator; Nancy E. Schwartz, a marketing consultant; and Felicia Carr, director of online communications at the National Parks Conservation Association.

The speakers mentioned more than a dozen resources that can help nonprofit groups. Here they are:

• The Pew Internet and American Life Project offers up-to-date research on how Internet users are navigating the Web — and what they’re doing online.

• A recent Harris Poll of Facebook and MySpace users offers demographic information about some top social-media sites.

• The Net Wits Think Tank offers four useful tip on how nonprofit groups can make the most of Facebook.

• A global fund-raising event called Twestival got Twitter users involved in raising money for the group Charity:Water.

• HootSuite allows you to schedule your posts on Twitter — or manage multiple accounts on the site.

• CoTweet is a site that makes it easier to use Twitter if your group has multiple people who contribute to your Twitter feed.

• Ms. Schwartz’s recent blog post offers thoughts on whether nonprofit groups should have policies on their use of social media. Another blog post, by the social-media expert Beth Kanter, also weighs in on the idea of social-media policies.

• We Are Media, a project of the Nonprofit Technology Network, offers a social-media starter kit for nonprofit groups.

• Ms. Schwartz offers a podcast interview with Dave Evans, author of Social Media Marketing in an Hour a Day.

• A New Orleans pizza company discusses how it used Twitter to set a single-day sales record.

• Causes is a Facebook tool that many organizations use to raise money on the site.

• A new study from M+R Research Services and the Nonprofit Technology Network offers an in-depth look at online giving patterns.
