In my effort to deal with the mailing list name problem (it uses firstname.lastname@example.org, I want users to use email@example.com) I've gone through and hand-edited the HTML pages for Mailman, and the various editable preferences (that I could find) in the config pages.
Nevertheless, there are still some things I can't figure out how to fix, notably the body text of the welcome email. It prepends my customized message at the top, like it is supposed to, but the body text refers to the mailing list by its verbose name. Is there some way I can edit that text? It is likely to confuse users, even with my ALL CAPS WARNING at the top of the page suggesting they use the short-form names.
I don't want to simply delete the text of that message -- it has important info about passwords, the archive, etc. but I'd like it to be more user-friendly.
