[Evolution] Discourse and the situation for Mailman lists hosted by Gnome.org

[dfc <chernoff astro cornell edu>]

What other Gnome lists (analogous to evolution-list) are currently
scrambling with the abrupt decision to switch to discourse?

This will be helpful to know if one is trying to convince a major
organization to step up and host evolution and possibly brethren
too.

Thanks,
David
