Hi, I have a question about the way to use "OpenStack Powered" mark. Maybe this question is stupid, and sorry if so. According to https://www.openstack.org/news/view/59/two-milestones-mark-the-beginning-of-the-openstack-interoperability-era , 14 companies have already gotten the mark by passing the interoperability testing. Our company will provide system integration services for building private cloud environments for customers. These clouds will be based on OpenStack distributions which have already gotten the mark. In this situation, can we use "OpenStack powered" mark when advertising our integration services? Or do we need to pass the interoperability testing by ourselves? Thanks Ken'ichi Ohmichi
