GameFAQs Help: If Your Work Is Not Accepted

• Improper Formatting
  GameFAQs does not accept files written in HTML, in proportional-width word processor fonts, or using word processor features (such as images and varying font styles). These kinds of files are generally not even reviewed for content, as they cannot easily be converted to plain text, which is the format for 99% of all files posted on GameFAQs. For more information, see the Composing Your Guide help file, which will explain how to properly create your file.
• Low Quality/Content
  If you file has little or no gameplay information, multiple grammar and spelling mistakes, or a hard-to-read layout, it will likely not be posted. Very short FAQs (under 10KB) are rarely posted, and files in ALL CAPS or no caps won't make it online either.
• Unacceptable Guide Type
  Multiple-game guides, FAQs for unreleased games, placeholders, online cheats, fictional works, and a few other types of files are not posted on GameFAQs. See the full unacceptable file list in the Before You Start help file.
• Oversaturation/Incompleteness
  Once there are multiple complete guides for a game, incomplete guides are no longer accepted, and new guides must match the quality and content of what has already been posted. See the "Will you accept a FAQ..." section of the Before You Start help file for specifics.

Also, you should try asking those on the FAQ Help message board for a peer review. Other contributors can usually spot obvious problems in your guide that you might have missed.
