Rules

Donors can join any GIVGroup, and as many different GIVGroups as you wish.
You can donate as much as you wish (and all funds will go to the charity, less the small payment process fee)
You can donate to any one GIVGroup as many times as you wish. However, for qualifying for the GIVGroup challenge goal (# of participants), you will be counted only once (per joined GIVGroup).
As soon as the challenge goal is met (the number is achieved by the closing date), the sponsor’s donation is made to the indicated charity.
You may also donate directly to the charity, but this will not be counted in the GIVGroup to help achieve the giving goal to trigger the matching gift.
