If you want to write professionally, do as we professionals do: use Microsoft Office Word, or Microsoft Publisher. Any lesser software marks you off the list as "non professional."
"Shareware" and "Freeware" are the kiss of death to a budding writer: once it gets around to assorted editors that you are so sloppy and unprofessional that you will not invest in your career, then you will not invest your time and effort into professional research, either.
They have seen it before, time and again. Sloppy leftists writing sloppy copy for sloppy fees. None of that slop sells, and they are getting tired of putting more slush in the slush pile.
Writing is not a career that leftists actively pursue. They wind up driving tour buses or working at McDonald's because they are ignorant of financial planning.
We working writers live on chicken today and feathers tomorrow, so we know the value of saving for the future -- which of course, "Smacks of capitalism" to leftist liberals.
I realize that repeated publication with major national magazines and 28 novels sold in the last fifteen years makes me what leftists call, "A stereotypical rightist hack," but it pays the bills and puts fun things to read into the market. Boring leftists never measure up, so fine, stay with shareware.
