CCing to the list ( if you are new to this list, messages come from
the sender address, you have to use "reply all" ( at least in my MUA,
web gmail ) to make your replies appear in the list ).

Do it, and do not forget to try the straightforward solution ( sume of
cases ) given by Ladislav Lenart above.I normally prefer to do this
kind of things the way I pointed you because the queries are simpler
and normally only the first one takes time, and using count tends to
be the faster way to extract the relevant data ( the rest of my query,
after the first with, is just moving data around for pretty-printing (
or pretty-selecting ).
