Have you worked on a project you would like to showcase? Maybe you want to share your expertise of a particular module? BUT You have never presented before? You do not have enough material for 45 minutes?
Lightning Talks could be for you. They are a highly appreciated format that consist of six 15 minute talks back to back. As well as being tremendously interesting and entertaining for attendees, they offer an unequalled opportunity for new speakers to present for the first time without going to the lengths required for a longer talk.
