The more members there are, the more DVDs available to other members. So the more likely it is to find ones of interest. So to encourage as many people as possible to register and to post DVDs for exchange, you don’t have to pay a penny to register or to use the facilities. Perhaps we’ll start charging a small fee once there are lots of members but by then you’ll have found out just how valuable your membership is and will want to continue it. And of course if, by the remotest chance, you don’t want to pay to subscribe you’ll be under no obligation to.
