I cant find any option to refer friends via the website. this would be a cool feature that could enable you to grow, and also reward those members who refer friends.
i get emails all the time from companies stating that if i refer a friend, and that friend signs up/makes a purchase, then some kind of reward is given to the referrer. you could do a free month or half off a month, or some kind of similar credit for each friend that is referred and signs up. make sense?
