Just have fun!! The more you think about it, the more you are going to stress about it. I also disclose before any of my presentations and trainings so I get it out of the way and I can focus on presenting. My stutter is moderate and random, but oh well, I just keep going. I stop, take a breath, and keep presenting. I also use humor in my presentations/trainings because, for me, it helps me out. I wish you great success and you are going to be AWESOME!!!!!
