I agree with Walker, and with this list, unfortunately, when you hit REPLY ALL, you only get the madcitychickens group e-mail, so you actually have to cut and paste the sender's address if you want to send something to them directly.
Other groups I am on are set up so that if you hit REPLY ALL you get the sender as well as the group in the "send to" field, so you can simply delete the group. I wonder if this one could be changed to that sort of thing? It would make replying to the sender only much more user friendly!
