Eighteen years ago.
My proof reader was ill...(and eventually died)
There was a book contract for 10 chapers in a 28 chapter book, due in six months and a dissertation hanging over my head.
My spelling was abismal....this "forced me" into computers. I rented a computer at a church, weeknights, from 8:00pm...until whenever I finished, at 5.00/hour
And as they say...THAT made all the difference.
Dyslexia led me to computers (and on to becoming a better speller.)
