Nobody needs us to place them afterward. There is a church down the road running a service on a system nobody was ever trained on. There is a band three months old that has never had anyone on the board. There is a school with a stage and a cabinet of equipment nobody opens. Those rooms are everywhere, and every one of them is short the same person.
So the two asks on this page feed each other. Somebody who already runs sound gives a few hours, and a student gets through the hands-on end of the course. That student walks into a room that has never had a sound person and becomes one — and then they are the one standing behind the next student.
Each one opens the door for the other. That is why both asks are here, and why the whole curriculum is published in the open for anybody to take and teach.
