It is definitely very very useful. Thank you very much for putting this

I have tested it and notice that I need a few changesmods:

1. Give it the -l option to specify a listname (yes, my server has several
2. The current -l should probably be changed to -f for specifying the
subscribe filename/path
3. Since the subscribe log has dates, maybe -d should instead be used to
parse for and then group by month??
    Or perhaps you can add an option to specify the month you want, like
Jan, Feb, so a '-m Nov' will give the join/leave for November..
4. To make it a little fancier, you can display the results in some
tabulated format:

Mailman Subscription Report for $Month
LISTNAME ---------------JOINED---------LEFT
list1                                15                    2
list2                                  8                    12

With the MONTH option available, I can then simply run it from cron to get
reports like:
mydate = 'date +%b'
./subscribe_log.py --f /usr/local/mailman/logs/subscribe -l listname -d
$mydate | mail -s "Mailman Subscription Status" john at doe.com

So far that is all in my request.

Once again, thank you very much.
