While researching regex ideas, I did see your post at Re: Insert colons into a MAC address which is sort of similar to this problem, but I couldn't see how to apply it to leave off the final "." in my regex.

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • 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.
  • Please read these before you post! —
