I am not sure if this the right forum, forgive me if not I just gave my best guess. But on topic! I am going to a writer's con (Midsouthcon, March 9-11th). I don't have any published work, and only a rough draft even completed, so I'm not sure how much I really have to offer. What should I do to build connections for where I am? And how should I do that? Business cards, elevator pitches? Other stuff I don't know about?
