When a guy signs up for mygirlfund, he receives three free messages. Since they are free, they do not have any cash value. You will see free messages with a zero value in your fund pages.
Although you do not receive a financial contribution to your fund for these messages think of them as hot leads. A contributor is interested in initiating communication with you and it is very likely he will be interested in contributing to your fund. To maximize your earning potential it is best to reply to every message that is sent to you in a timely manner. Free messages will expire in four days.
