How to keep email identities concealed?

[statpick]

Is there anyway to compose message to a group without showing the individual email identities?

I would prefer to be able to send a block message to the group so that everyone's identity is concealed.

Hey -- thanks!  That was a pretty easy solution -- and I appreciate you taking the time for such a mundane problem & solution.
