What I've done for this is to simply remove the password fields from the 
form. Then it autoassigns you a password.

You can see that here: http://lists.acm.jhu.edu/mailman/listinfo/acm

(Viewing the source, I see what I did instead was to put it in an HTML 
comment.)

I brought that trick with me to other domains, e.g. 
http://lists.openhatch.org/mailman/listinfo/devel

Contrast with e.g. 
https://mail.gnome.org/mailman/listinfo/asia-summit-list where the 
password form is visible.

It's fairly simple edit to the default mailman template, as I recall, 
and these changes I made have successfully stuck around across upgrades 
and more.

Users will still need to use the list password to do things like change 
one's email address on the list and a few other obscure things. My hack 
is just a UI fix that papers over the deep insanity of Mailman 
passwords, and I rank it quite high for cost-effectiveness. So please 
consider it! I hope it fits y'all's needs.
