Catharina Bethlehem writes "open-of-course.org is a new multilingual portal for free online courses and tutorials. On open-of-course all content is published as open content, so either it is in the public domain or under a creative commons license.
Through open-of-course we want to make it easier to find this kind of free information. Also we hope to stimulate the development of open content educational material.
The focus is at the beginning mainly on educational material for open source software but as we grow, more subjects will be covered.
Open-of-course is looking for people that want to contribute to this free educational portal. There are many ways to do that. More information can be found on the website."
