Joining means you can take a more active role in meetings by giving speeches, performing functionary roles including Toastmaster, Grammarian, Timer, Improv Master, Table Topics Master, and Speech Evaluator, and even run for office in the Club.
The membership fee is $72 for six months (half goes to Toastmaster International, the other half goes to the chapter). The first time you join a Toastmasters club, it costs an additional $22 for two books: The Competent Communicator, which has ten speech assignments designed to help you improve your speaking skills rapidly; and The Competent Leader, which has assignments that help you build leadership skills.
