Hi All, I'm running a project which is a OpenStack related project currently. My questions is: Is being part of Big Tent a requirement before a project can follow one of those 3 release models(cycle-with-milestones, cycle-with-intermediary, and cycle-trailing) as described in http://docs.openstack.org/project-team-guide/release-management.html ？ Thank you B.R., Zhijiang
