This may seem a little obvious, but make sure that your script produces valid output no matter what the input. (I say this from first-hand experience ;-) Even if you think that you have thought of every conceivable scenario, make sure that you have a default behavior "just in case".

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
