What is the password to my Mailman list? 

When you create a list via the do-it-yourself page, it doesn't send
the standard email with a list URL and password.

However, what you can do to get into your list is log in using your
MIT personal certificates.  You can do this by going to an "https:"
url that uses ":444" in the name.  As a specific example, if you have
a machine with your MIT personal certificates, you can visit your
list's password changing pages by going to the web page:

  https://mailman.mit.edu:444/mailman/admin/LISTNAME/passwords

Once you get here, you will be able to use the text entry boxes
on the page to set a (new) password for your list, and you will
be able to use that new password in the future.
