Re: Mark articles/replies in thread in which I replied previously

I increase the score of threads that I reply to using:

  (add-hook 'message-sent-hook 'gnus-score-followup-thread)

The docstring says:

  Add SCORE to all later articles in the thread the current buffer is
  part of.

This doesn't mark them, but might be useful instead of that.
