This is a request for comment. I've posted a draft proposal for the license update here:
http://meta.wikimedia.org/wiki/Licensing_update
It is not intended to be final, but I hope we can arrive at a final version by February 1.
We would appreciate questions, comments, feedback. If there are obvious edits which you feel would make the proposal clearer, please do go ahead and make them, but please be careful about edits that substantially alter the proposal itself.
Thanks! Erik
