2) Better mailing list subscription management (subscribe/unsubscribe
to many lists at once) and better mailing list archives (searchable,
show whole threads like google groups/forums)

1. Better mailing list subscription/management options, especially for
   new users. For example: someone should be able to subscribe to a
   mailing list also without being member of that team; unregistered and
   logged out users should be able to know how to subscribe from the
   team page.
