PS. Any actually coherent and sensible reason the reply-to seems to go to 'individual user' rather than 'chatty mailing list'? I never understand that...
Ruth,
If you're using Mac Mail, try hitting reply all which will give you both the list email and the personal email so you can delete the one you don't want to reply to.
It's a bit of a fudge, but it works...
Thanks,
Dave
