It is, but the traffic is low so I don't watch it too closely.  Please 'ping
barry' to get my attention about Mailman 3 issues.  I'm always online during
working hours EST (currently UTC-5), though I will be offline Thursday and
Friday for the USA Thanksgiving holiday.

One thing to keep in mind.  Since the a6 release, a new version of buildout
was released too.  This bug affects Mailman:

https://bugs.launchpad.net/zc.buildout/+bug/659231

A workaround is to add this to buildout.cfg:

include-site-packages = false

and this fix is in the bzr trunk.  However, even with this change, I am having
trouble building a6 from the tarball, either inside or outside the
virtualenv.  I don't know what the problem is.

I have not had to add these.

This looks related to the line added to a7's buildout.cfg above.  However, as
I mentioned that doesn't seem to fix the problem for a6.

When I build a tarball for a7 from the bzr trunk, I have no problem unpacking
the tarball and building it using the instructions on the web, with or without
a virtualenv.  I'm doing all this on Ubuntu 10.10.

The best advice I can give right now is to grab the Bazaar trunk by doing:

bzr branch lp:mailman

and running it from there.
