Hey Joe,
I also forgot to look up people from the forums. It didn't occur to me at all during the con, I was in a constant daze of excitement, sugar-rush and lack of sleep. :)
As it was my first GenCon I expect oversights like that to happen. Who knows, when I go back in a couple years we may see each other there and shall barf forth apocalyptica together! :D
I hope it went well for you. I for one enjoyed running Apoc World @ Games on Demand as well as Monsterhearts and Fiasco.
