Netiquette question

[Matej Cepl]

Hi,

just a question: what is better when answering to answer given
on the list? Should I reply to the list (as I do all the time) or
sending answer to originator of the question with kind reminder,
so that he should send a summary (as his "payment" to the public
for getting advice for free) to the list? Or we are too small,
that volume of mails is not an issue, and I should not bother?
