Gophering is a good way to way to get involved in conrunning and meet fans. You don't need to know anything about cons or fandom to do it. Very often, you can volunteer once you get to the con (gophers who volunteer early sometimes find themselves concom instead). The kind of jobs gophers do include checking to be sure everyone who enters some con function has a badge, helping out with foodservice or cleanup in the consuite or green room, setting out tent cards in program rooms, assorted toting and hauling and running errands on behalf of gohs.
The term comes from mundane slang, where a gofer is a junior employee who “goes fer this” and “goes fer that.” Fans liked it better with the [[H]]] in it.
