"PS. I put this through the spell checker and it did not like 'would-be-poster'..."
It might be because the Mayhem spell checker cannot handle hyphenated words. It might also be because you used one too many hyphens between the "be" and "poster".
In a similar vein, we were gently reminded soon after this forum began that the reason for many of the poor spelling and grammatical errors is not down to laziness on the author's part, but merely down to the fact that many simply did not have access to schooling or education. Also, a fair amount of older members had to leave school at the tender age of fourteen - sometimes younger - and had to go out into the big world to bring money into the home. Ergo, were robbed of the chance of learning even the very basics of English.
In this modern world, there really is no excuse for any schoolkid not to learn how to pen a legible letter... not unless the teacher's teaching them are themselves just plain dopey.
