Someone asked me recently to define what I do for dragon*con tech staff. I thought about a lot of answers, all of which encompassed part of the job, but eventually I hit on a word that I think nails the entire thing in one: "logistics."
My job is to know tech staff, inside and out, from the moment they sign up. Their biographical and geographical info goes in the database, but the rest goes inside my head. What are they like? Who do they work well with? Who brought them on staff? What skills do they have? What other departments do they like to work with?
