Tech Crew

As distinct from logistics, this is the designated group of people to assemble and operate certain equipment. For example a complex AV rig with projectors, sound, mic, and mixer board, will need specialists to operate it, separate from those who move and store it.

Techno-Fandom

There is an email list of people who frequently manage or staff the tech function at various cons. One can subscribe by going to http://two-step.netbusters.com/mailman/options/techno-fandom. There is a bit of useful information on this subject collected on the same server at http://techno-fandom.org. Note, techno-fandom is often mistaken for an organization or an institution but it is really just a set of people on an email list and a collection of partially overlapping circles of friends and acquaintances, some of whom like working tech at cons.
