IDEA has a process by which you can apply to be a presenter, and here is a link http://www.ideafit.com/application-intro.
You had already asked the question about creating a certification or license. Or do you mean a trademark? There are processes as well http://www.uspto.gov/trademarks/basics/.
One thing to keep in mind: if you have something really unique, you may very quickly look at how to protect your intellectual property because people will pick up very rapidly and may end up being on the market with it before you are. With that in mind, you may weigh the options of presenting at a public forum before having secured some protection.
