When writing or editing preliminary program copy, remember that you are writing copy to market a product. You must not only provide the required information, but also present it convincingly. Write the copy as if you had to justify program attendance to your boss. After writing or editing the copy, read it aloud or show it to someone else. More is not necessarily better.
Nothing is more intimidating to a reader than a long, jargon-filled description.
Keep it simple. Keep it short. Use the active, not passive voice. Write your copy and then rewrite it, edit out words and phrases that contribute nothing. Frequently, programs lend themselves to excellent publications.
