One guideline to keep in mind:

  > If the original title begins with a number or number + gratuitous
  > adjective, we'd appreciate it if you'd crop it. E.g. translate
  > "10 Ways To Do X" to "How To Do X," and "14 Amazing Ys" to "Ys."
  > Exception: when the number is meaningful, e.g. "The 5 Platonic Solids."
