Creative Commons are a charitable organisation, working and researching how to best provide creators of original works with options for others who wish to use or re-use their work.
There is a whole wealth of information, advice and support provided to assist in understanding the bewildering world of international copyright.
I support them and I have been able to benefit from their advice and information so that I could find the best way of ‘protecting’ and ’setting free’ my own original works.
They have a 2007 campaign underway. They are helping anyone who wants to do anything on the web in a huge way, so it is a great organisation to support or to donate.
