Please do not send separate copies of replies to everyone who has posted 
in a thread.

Use Reply To List, if your email application provides that option, or, 
if you use Reply To All and that includes multiple email addresses in 
the To field, delete all email addresses from the To field, apart from 
the list email address.

Why annoy people through multiple reply copies, and, waste bandwidth of 
your victims?
