    Annabelle Day

    A picky, compulsive proofreader...

    United States - Portfolio: 10

    Where have all those compulsive, "old-fashioned" proofreaders gone? You know, the ones who catch the pesky grammatical errors, who know how to weed out unending commas and delete errant apostrophes, who understand how and where to use hyphens, who pounce on messy line breaks. Sadly, we have become an endangered species -- proofreaders and editors so immersed in our profession that we can't control ourselves. We compulsively proofread menus, TV commercials, and ads that appear in our mailbox. I am just such a proofreader and proud of it! I LOVE proofreading -- the more detailed the better -- and I would appreciate the opportunity to work with you on your project.
