Yes, Gordon, I agree with reading it out loud. But not if there's anyone around! When you read it out loud, you're much more likely to spot missing words or duplicated words, as well as things that have just become garbled.
And Bluedolphin, thank you. Changing the font is something I hadn't thought of. But I realize that when I enter an article into the BOL system and see it on the screen, errors leap out at me that were completely invisible during my editing. I will try changing he font before entering them, since I don't have to be online for that.
