Donor Challenges
When you set up a Donor Challenge, you agree to donate an agreed amount if a certain number of other individuals choose to donate as well. For example, you could agree to give $1,000 if 20 new donations are received.
Dollar Challenges
When you setup a Dollar Challenge, you agree to donate an agreed amount if others contribute a certain aggregate amount. For example, you could agree to give $5,000 if others give $15,000.
