After discussing this in the community forum and emailing all wiki contributors, I am happy to announce that the Mahara wiki is now licensed under the Creative Commons Attribution-ShareAlike 3.0 Unported License.
Should you have any questions about the process or the rationale behind this change (which are both similar to the Ubuntu wiki), please feel free to email me at francois@mahara.org.
Cheers,
Francois
