I am not so good speaker who can be motivating to an audience of 50 or 100. I can teach things to motivated people. Moreover when a person/contributor speaks it is much more effective.
DVDs may or may not be provided. All we need is a good speaker, who can show things, impress people and make them contribute. I hope you understand.
