This is not my first site built on K2. The site was originally a Japanese Polish community was built on Joomla 1.0. In 2009 I made the migration of the old CMS to version 1.5. As the editors has grown, I decided to implement K2. It is now the latest release of K2 and Joomla. For sure I have a lot of work because of migration have made less than a month ago. I want to thank the author / authors of K2 for an excellent product.
