I am relatively new to OpenStack development as one of the developers on the unified PHP SDK for OpenStack .
We were recently discussing about a mailing list for the users of this SDK (as opposed to it?s contributors who will use openstack-dev@). The purpose of such as mailing list would be for users of the SDK to communicate with the contributors as well as each other. Of course, there would be other avenues for such communication as well (IRC, for instance).
Specifically, we would like to know whether existing OpenStack projects have mailing lists for their users and, if so, where they are being hosted.
