[Mailman-Users] Documenting a list-specific change

[Drew Tenenholz]

All --

I hope this is simple.  I changed the preferred_language for a list via the admin web interface last week, and some downstream processes are no longer working.  Before I blame the change in the list for the failure, I need to know rather precisely when I made that change (i.e. Monday vs. Thursday).  

Is there a  simple way to figure this out?
