[Gmail-Users] automatic sending to list of people

I am going to Australia this summer with some other kids, and we are
leaving our parents at home. I was wondering if there was a way to send
one long email back from Australia to a gmail address, and when it is
recieved, it automatically sends this email to all the parents. Kind of
like automatic forwarding to a list of 12 or so people. Please let me
know how to do this, or if I need to supply you with more information!
Thanks!
