Nonprofit organizations may support a variety of causes, but the one thing they all have in common is a desire to serve the public good rather than to make money. Some, however, face a challenge in finding donors and sponsors to ensure a continuous flow of funds, making it necessary to hold events like a silent auction fundraiser. How exactly does this work? Kathryn Lemmon of Yahoo Contributor Network gives a lowdown:What makes the event "silent?" A silent auction is one without an auctioneer. During the auction period, (a set amount of time such as 4-6 hours or all day Saturday) bids are written down on a sheet of paper. The bidder can see all the previous bids logged onto the sheet. At the end of the auction, the highest bidder wins the item.
