Rememeber, you are not alone. There are on average 500 list members, and although many do not post, many more do. So the chances are, there will be several others seeing the message(s) at the same time as you, and thinking the same, 'Do I need to respond'? Do i have something that will be original to add?
If you have several messages to respond to on one thread, consider combining your responses to save bandwidth. (Remember the email header is often longer than most short messages).
