Here is the recognized US definition of freelancer:
A freelancer is an independent contractor who earns wages on a per-job or per-task basis, typically for short-term work. Benefits of freelancing include the freedom to work from home or from a non-traditional workspace, a flexible work schedule, and a better work-life balance.
Sometimes in certain areas (such as journalism) free lancers evan work for free to build up a portfolio or a reputation.
This is not that. This is entirely a hobby. It is entertainment in these, my declining years, with no expectation of a reward of any sort, except, perhaps, to satisfy a degree of curiosity which, fortunately, has not declined with the passing of the years.
