In 1995 I was an expert in setting up Trumpet Winsock, paid to consult on its installation and configuration - even though I had never once installed it myself.
That is to say, I was a tech support lackey, answering the phones and talking to dozens of dialup ISP users daily.
It was a small company, and of the three techs there, none of us were Windows users - two Linux, one Mac. Someone had helpfully printed screenshots of Winsock's various dialog boxes and taped them up around our cubicle. It was enough.
