People are much more likely to join a cause if they are invited by people they know. This is a great example of the power of social networking. Our website provides the capability to invite friends. Invitations are tracked and you may view your invitations at any time in an effort to see which of your friends has accepted your invitation and registered and those who have not responded.
Invitations expire after 30 days if your friend has not accepted. You may of course, invite them again anytime.
