Using American sign language, Greg Crapo, right, director of de l'Ep e Deaf Center Inc. in Biloxi , Miss., helps Shanda Bennett of the Environmental Protection Agency at NASA's John C. Stennis Space Center spell out her name. Bennett is joined by colleague Charles Kennedy during a tour of charitable organization displays for the kickoff of the Stennis portion of the 2009 Combined Federal Campaign emphasis on Oct. 29. The CFC is the world's largest annual workplace charity effort. Contributions to the campaign support organizations providing health and human service benefits throughout the world. Stennis employees give tens of thousands of dollars through the campaign each year, including a $198,000 in gifts in 2008. This year, the Stennis goal is $200,000. For the kickoff, a number of charitable organizations provided displays at Stennis, providing employees an opportunity to see - and choose - where their contributions can be directed.
