Through a crowdsourcing website that Darien nonprofits are beginning to use, you can now contribute to a specific cause for a specific group in town, and one of the first local nonprofits to use it is At Home in Darien, which wants $1,065.74 to replace brakes and tires on its van for seniors. Actually, At Home now wants $565.74, after the law firm of Wofsey, Rosen, Kweskin & Kuriansky gave $500 to the cause. Joe Pankowski Jr., chairman of the Darien Aging Commission, is a member of the firm and presented the check to the Community Fund of Darien. The rest of the money will be raised through a new website, The Impact Vine, an online giving website developed by the Community Fund of Darien that lets people support projects they care about. Impact Vine works as a crowdfunding platform for lower Fairfield County nonprofits to use as a tool to raise money for projects in their communities.
