[Openstack-i18n] translation team communication, how to create mailing list

Hi, to get back on an older topic, e.g. see http://lists.openstack.org/pipermail/openstack-i18n/2015-September/001380.ht... Zanata apparently doesn't have the capabilities to send messages to the translation team (the built in chat is not too helpful) and it doesn't seem realistic to expect such a feature in the near future. Since the German translator team is growing and to have some appropriate forum to discuss language specific issues and agree on standards, I thought about finally managing an email list, something like [Openstack-i18n-DE]. Would anyone know how to request/create an email list on lists.openstack.org? -- Thanks, Robert
