Thanks! I'd known there were sub-LKML lists, etc., but I hadn't realized that there was an actual mechanism -- and a script, to boot -- in-place to facilitate this. (And now I feel a bit guilty about e-mailing the maintainers directly -- and the list not at all. Won't do that again.)
And, as a side note, it's columns like this that make LWN the amazing resource that it is. Kudos to Jon for continuing to find new ways to inform the user community, and build bridges between it and developers.
