[Mailman-Users] Removing "To post to this list . . ." from confirmation e-mail

[John Hughes]

I'm trying to set up Mailman to use as a vehicle for distributing a newsletter.
I don't want anyone to think they can post messages to the list address.

I have figured out how to modify the HTML for the public list pages. How do I
remove the "To post to this list, send your email to..." from the registration
confirmation e-mail?
