Nice to meet to you, I'm developer stuff of Media Channel in Japan.
Our company, Media Channel develop Concrete5 for clients of University, local government and Social Welfare Service Corporation in Japan. We also assist their business through our developing Web site and analyzing site's data to improve user's access.
Our account is also registered at Japanese Concrete5 Organization. But information is less and not expert than US's. Frankly, Concrete5 is not used and not know among Japan, but C5 has something potentials to create powerful CMS that clients resolve their business problems, I think.
Getting to know C5 among Japan and making C5 more powerful CMS for clients business, I utilize US cocnrete5 Organization and Forums.
Thank you for reading.
