Then, I wish you had changed the Subject header and started a new thread,
(or that Bob had had the good sense to do so).  I've just _now_ done
so, setting new Subject and deleting header In-Reply-To.

What Bob did is called thread-hijacking, distinctly non-helpful to
Kevin's aim of trying to arrange a July speaker.  Quoting a Web forum:

  Please do not hijack other people's threads

  Authors who begin a post do so for a reason -- they want to discuss or
  talk about that one thing. Sure, discussions evolve and can move beyond
  the original poster's topic. But that's a natural process that moves
  slowly over usually many pages of posts. Hijacking occurs much more
  rapidly, and the entire thread often devolves from there quickly.

  Most people who engage in this behavior probably don't realize what
  they're doing, and don't mean to do it.
