Mark,
A suggestion, you might want to change this page:
http://wiki.list.org/pages/viewpage.action?pageId=17891458
...to something like:
"If you have Mailman 2.1.16 or newer, set
ALLOW_FROM_IS_LIST = Yes
in mm_cfg.py and then restart mailman. The from_is_list setting will then appear on the Admin / General page. Set the list's from_is_list setting to either [...]"
I didn't want to edit mm_cfg.py and restart mailman until I knew what I needed to change for from_is_list. I did a fair bit of googling and tail chasing, only finding discussions about ALLOW_FROM_IS_LIST, until I found a page (the dreamhost mailman wiki) that explicitly said from_is_list should show up on General/Admin. Then I guessed that editing mm_cfg.py and restarting might make it show up.
