I want two articles with the same subject to be sorted together, even if neither of them contains a References header. Is it sufficient to set gnus-summary-thread-gathering-function to gnus-gather-threads-by-subject to achieve this, or is it also necessary to set gnus-summary-make-false-root? kai -- I like BOTH kinds of music.
