All papers should be double-spaced throughout, (including the reference section) with one inch margins all around. Do not add extra lines between paragraphs or sections. The font should be 12 pt and you need to use a "serif" type style (with the hooks and curly-cues), such as Times or Courier. All paragraphs should be indented half an inch, NOT five spaces. Only one space should be added between the period at the end of a sentence and the first letter of the next.
