Chamara,
i believe we may have to create a couple of more lists on the days ahead of us. to have a fine grained control over the topics/lists/discussions.
so that will ensure that the correct person is getting the correct mail. ie if there's anything in regard to the the Web/UI , only the Web/UI engineer, you and your team should get the mails in regard to that... without disturbing the others :P
that's the plan. for the time being , this is sufficient ;) [i have this bad habit of thinking and making decisions in the future .. lol]
