I've gotten a couple of Read-Only files lately. Frustrating. For one, it indicates a lack of trust and professionalism (akin to noting copyright on your manuscripts.) But mostly, I read stories with my fingers on my keyboard. I often make little fixes and word switches, insert punctuation. In other words, I edit stories as I read. It keeps me engaged and lets me explore the amount of work a story will take to bring it to publication. I don't save these edits, but it's my little quirk as an editor. I do this more intensively during our voting process.
Plus, if we do take the story, you're going to have to send me another file before I can edit it. In my experience, those exchanges take a few days to complete and can set me off-schedule.
Indulge me in this. Send us regular .rtfs please. We aren't interested in stealing stories; we're interested in buying them.
