After subscribing, I noticed that http://lists.openstack.org/cgi-bin/mailman/options/openstack-sigs only lists one topic category ([meta]) whereas https://wiki.openstack.org/wiki/OpenStack_SIGs lists four. I assume that's because it's still very early days for the SIGs and the PTG has been swallowing everyone's attention recently, but it would be nice if the inconsistency here could be addressed at some point. Thanks! Adam
