Use boilerplate paragraphs. Boilerplate originated in newspapers. Late at night, as the production staff raced against deadline to compose the pages of the newspaper, they used boilerplate to save time. Create a file for boilerplate in your computer and place in it copies of all the boilerplate paragraphs you use in proposals, press releases, reports, memos, and letters. When you need to use one, simply copy the appropriate section and paste into your current document.
Editors like to be told when a story ends.
Perhaps it dates back to all those years of studying the newswires, where an editor was expected to read a virtual parade of stories every night. Stories flow across the wire in a never-ending stream, and so, editors are trained to look for end marks. The next time you send a press release to a newspaper or magazine indicate when the press release ends by typing an end mark after the last paragraph. Give the end mark its own line and center it. Editors will appreciate the gesture.
