Problems dealing with round table discussions and making a "good first impression"...

Simply stating that you stutter at the start really helps. Unfortunately "jumping" into the conversation can be particularly hard. I was once "scolded" for bringing up something that had already been "tabled" .... The reason I was late was that I had blocked, and by the time my remark came out the conversation had already moved on... For this reason, your might both mention your stutter AND the fact that you will raise your hand to ask for your time when you have something to say. If they don't give you the time THEY are the ones who will look bad to the audience..

One more thing: Mentioning your stutter and how you wish to be supported at the round table GUARANTEES a GOOD FIRST IMPRESSION. You will be admired for your courage and straightforwardness, and people will be even more interested in what you have to say. It beats any attempts to hide the stutter and to hide any internal struggle.... every time.
