I can't remember if I technically counted myself as full time in the questionnaire, I remember thinking about the question, and maybe said No (see below); but I'm early-retired, and my micro income doesn't match my superannuation. Other people could be in a similar position, and said they were full-time microstockers in that they don't do any other paid work, but their pension could still be more than they earn on micro.
Also there's the question as to whether Alamy counts as micro on that questionnaire. I noticed there was a separate question, but again wondered whether dividing shooting time between Alamy and micro meant you couldn't be a full-time microstocker, which if I said 'No' was the reason.
