Actually having a buzzer system is a great ploy because everyone who has played will recognize it immediately. Another successful draw is a TV with a VCR playing a local quiz-game. Have the first meeting time and place already established so you can give out fliers with this info already available. Put off elections so that the focus stays of the activity, not on power issues. If you do not have a buzzer system, lobby the SGA to purchase one, focusing on the academic potential and drive of your club.
Many clubs loan out their buzzers to other student groups for annual trivia events.
It is wise to mention this if you know of potential events who could use your buzzer to back your request. Some schools have administrator-run annual QB competitions. In some cases the administrators will be helpful in organizing your club. Many administrators have a dim view of how this activity really works. Few are aware of the circuit of college teams who play one another monthly, and some have bizarre misconceptions about the circuit.
