Most shows have a stage for workshops and presentations.  And most show managers are constantly looking for great material to go on those stages.  So take advantage and volunteer to be a presenter, but ONLY if you pass these criteria:
A. Your subject has to be not just informative, but interesting or important enough to draw a broad audience.
B. It has to have a great title.
C. You have to be a really good presenter.
D. It has to be interactive, demonstrative, or participatory.  In other words, standing there and talking ain’t going to get it.
E. It should not last more than 20 minutes.
F. It cannot be a commercial for your company.

And even if you think you have all these ingredients, don’t be offended if the show manager says ‘thanks but no thanks.’
