[Mailman-Users] Mystery with user_option URL

[Allan Trick]

Help!  I set some lists up a year ago and on most of them a note I append 
appears like this (it's entered into "msg_footer" on the Non-digest Options 
page):

   Changes to your subscription may be made by visiting 
http://www.prin.edu/mailman/options/2014/atrick%40prin.edu.  If you are on 
more than one such Principia mailing list, click "Change globally" to apply 
any changes you may make to all of your subscribed lists.


I set up a new list just now and the footer appears this way on this new list:

    Changes to your subscription may be made by visiting 
%(user_optionsurl)s.  If you are on more than one such Principia mailing 
list, click "Change globally" to apply any changes you may make to all of 
your subscribed lists.


(It doesn't translate the user_option to a URL.)

Here's the instruction copied straight from the "msg_footer" field of the 
list where it IS working right:

    Changes to your subscription may be made by visiting 
%(user_optionsurl)s.  If you are on more than one such Principia mailing 
list, click "Change globally" to apply any changes you may make to all of 
your subscribed lists.


It looks just the same on the list where it's NOT working.  What have I not 
done right to get that URL to show in the messages?
