You shouldn't have to recompile Mailman when upgrading Python, unless
your Python 2.3 lives in a different place.  E.g. say you were using
Python 2.2.3 in /usr/local/bin/python and you installed Python 2.3 as an
altinstall in /usr/local/bin/python2.3.  You want to make sure that the
path to Python specified in things like your crontab match the Python
that you're using on the command line.

OTOH, we don't have any C extensions (I haven't checked the Asian
codecs), so upgrading Python should be pain free.  It was for me when I
upgraded from 2.2.3 to 2.3.2.

Added, and it'll show up on the websites next time I push out the pages.

Hmm, I definitely sent them information about install it.  Maybe you can
drop their webmaster a note about it?
