MOORHEAD, Minn. (AP) -- Students who worked on the Moorhead High School yearbook this year have learned a hard lesson about proofreading, after misspelling the Minnesota school's name on the front cover. A Forum News Service report says the 2013 yearbook arrived this week with the school's name spelled "Moorehead." Moorhead school officials say the mistake slipped past an adviser and two classes of students who worked on it during the school year. They finalized it after graduation and sent it to be printed this summer. The district can't afford to reprint the yearbooks. Principal Dave Lawrence says one option is to use a high-quality adhesive label to cover the mistake. District spokeswoman Pam Gibb says people feel very bad about what happened. The yearbook's title is "Moments Fade, But Memories Stay."
