Attend Public Speaking workshops. If there's a ToastMasters club in your area, join it. Improv can be another great way to learn how to get "less rigid" and more open with your communication style.
You get people to contribute to good causes by being able to influence them and not nag or harass or bully them.
Please get this book and read them because not all talk = influence:
I believe in what you profess but you are going about it the wrong way and even me who believe in your course find you annoying.
I'm no fan of NLP - it was intended as a personal development aid to deal with phobias and disorders, so was intended to be internally-focused. However, in my experience, many use it as a manipulative tool (externally-focused), which I dislike intensely. Makes me feel I'm being played, so recognising that is the value I derive from understanding it.
Dale Carnegie's book, however, is (my opinion) the best and most useful personal development book I've ever read.
For conferences: try to contact people that are going beforehand and talk about stuff over email. It's easier to follow up in person than to start from scratch in person.
