Great! How do you feel about taking the lead? I can help making sure we are in sync with WMF in terms of authorization, trademarks, etc.
Sure, although it seems everything legal takes forever with WMF... (its been over a week since I asked to get an NDA to see the api logs, no response :) )
Our contact in Codecademy told us that it is fine to start with a couple of very basic exercises to have the content published, and then we can add more content as we go & receive feedback. They also sent us the documentation to get started. I can forward all this to you.
Yes, please send.
