First time presenting at National CUE, super nervous, but I know everyone is as excited about tech as I am, so that helps :)

Its my first time presenting at National CUE, but I have a couple friends that have presented before and they have shared a couple tips with me:
1- Download your presentation to your hard drive just in case wi-fi goes down
2- Have screenshots in the presentation, just in case the wi-fi goes down
3- Enthusiasm is contagious, use that to your advantage
