After the final surge to get my CTM and moving office locations, I dropped out. I still do get a public speaking fix through some storytelling gigs. I'd rather not say which specific club (I like to think I am a wallflower) but that Toastmaster club is/was a fantastic supportive environment to practice public speaking. For the only way to learn public speaking is to actually do it. The value of the feedback (handwritten comments that you get after a speech) was tremendous - where else can you get honest supportive feedback - people want you to succeed. The fact that it was a corporate club that was not my company was a plus - felt safe to talk about whatever - no coworkers (except the one guy I carpooled with).
I go to #9351, Oratory Authority, a lunchtime club in Boston: http://ourdoings.com/oratory-authority/
