Ah-ha ;)

I'd not thought about that, but presumably, that's something that can be
addressed via the standard "stanza-in-a-po-file" method?

I've not got any multi-lingual lists running (yet), and am a bit in the
dark here (although, i rejoined the users/devs lists over an i18n
issue, oddly enough)

Fair point that, yes. Perhaps not in a listing per the current set-up,
but perhaps some sort of 'advanced/more' settings giving the options? I
dunno. I could see DB hackery becoming quite messy (particularly if
allowing given email addresses different settings for different lists)
