Well, it's not just Gale Force 9 that's looking for volunteers for the upcoming conventions. Shadows of Esteren is still pretty new, just getting into the hands of those that backed their Kickstarter, but they'll be headed to some pretty big shows and would like a hand.
So if you'll be going to Origins, Gen Con, or the UK Game Expo and would like to help out, drop them a line. You could end up running demo sessions or help setting up and tearing down the booth or whatever else the fellas have in store. They're willing to give free badges to those that can help out, as well as possible lodging at Origins.
