If you have a favorite charity, May 20 is the day to give and get your gift doubled.

A new Dallas-based website called DonorBridge, in cooperation with Center for Nonprofit Management and the Institute for Urban Policy Research at the University of Texas at Dallas, will match donations to participating nonprofits dollar for dollar during its launch date — May 20.

I know Healing Hands Ministry in Lake Highlands, Magdalene House, LIFT and Resource Center of Dallas are in on this because the three of them sent out notices, but because the DonorBridge goal is to get word out about all the nonprofits around, you’re likely to find your favorite charity there as well.

Donations must be at least $25 and matching will not exceed $2500 per donor. More about Dallas Giving Day here.
