I used to be a technical writer. What the heck ate my brain? I've been reviewing my entries and my format and my proofreading stinks! Thank goodness Dr. Mitchell is not alive to scream "Cut out the deadwood, Scat!" in outrageous red capitals in perfect cursive handwriting the margin. He would be horrified.
There was a day when slipping in an "as" for an "at" or an "an" would bring the black plague of death--to say nothing of an out-and-out misspelled word or repeated word.
I suppose you really do get what you pay for?
(Spell-check swears all these words are correctly spelled. I am doubtful.)
