I have just had to pull all my latest theme from the Moodle Repository because the Designer of the original FREE css template I used for each theme (which comes under the Creative Commons License) did not agree to my request to allow this template to be distributed under the GNU General Public License.
With my own situation in mind, regarding themes, I would like to challenge the current requirement set out by Moodle which states that...
"...All themes are offered under the GNU General Public License..."
I can appreciate that Moodle Open Source Software comes under the GNU GPL for the correct reasons, but surely Themes are more to do with creativity rather than software coding, unlike Open Source Software there is not source code as such, it's mainly to do with images and CSS which is covered by the Creative Commons License.
I'd welcome any thoughts on this topic as I am sure it is worth ironing out some problems which may need addressing sooner rather than later, especially when Moodle 2.0 theming will become more creative, more a work of art than source code.
