[Mailman-Users] Customizing Mailman

[Allan Trick]

I really like the way Mailman is configured 
here:  mail.python.org/mailman/listinfo/mailman-users.  Users can add their 
real name (optionally).  And when they change email addresses, it allows 
them to CHANGE, not unsub and resub (the way my own list works).  I'd like 
to add these two features to my installation.  Do I need to write the code 
to do that myself or has someone described how to do this somewhere?

Thanks for any help!
