Please, do continue, bringing many happy returns of the day! So many meanings and so many interpretations… through 50 years of collaborative development! From freely available, to accessible and inclusive… and global. Always inviting: to consider, to participate, to join and collaborate… Free from restrictions, but thoughtful with quality standards. Responsive and responsible. Reflective and always in the progressive state… It took 50 years for “traditional” higher education to understand what you are, why you are and where you are heading for.
