Hello,
here's a nice picture. The answer is in the mail http://www.flickr.com/photos/82626280@N00/172609494/
More seriously (or, maybe, less), I've spent a few minutes trying to figure out a problem a user was having (on irc). The problem was that she had configured the list to be in Spanish, but it kept sending welcome messages in English. I finally traced it to the Debian installation, which has weird symlinks: /var/lib/mailman/templates -> /etc/mailman
ls -al /etc/mailman/ total 36 drwxr-xr-x 4 root list 4096 2006-04-22 19:46 . drwxr-xr-x 95 root root 8192 2006-06-21 10:41 .. drwxr-xr-x 2 root root 4096 2005-10-04 18:17 en drwxr-xr-x 2 root root 4096 2006-02-10 17:46 fr
that's 2 languages only! whereas /usr/share/mailman/ contains all the templates (including es/, which she linked into /etc/mailman/ and solved the problem)
For me, if this is confirmed and not a weird thing on my and her Debian installation, it's a problem that should be solved.
