Starting an ASL Club

Starting an ASL Club - ...So a lot of people, when they were told that i am deaf, have mentioned that they have always wanted to learn asl however when they try to register for the classes, they were always denied since the class size is limited to 25 students per class. So i decided to start an asl club and have recieved permission from the college to do so. I have the constitution set up already and the basic foundation for the club, however i am not entirely sure as to how to teach people asl in a fun way... How does one make the class as fulfilling as possible for students of all ages and levels of asl?
