The Java Script libraries have always been free with a license that just requests attribution. Some aspects of the source code have been released - as has been an API to interact with elements of the community. The websites themselves are so interconnected with server features, the email server, and the database, that it would be tough to release much. Plus, since the community is expanding to work as a free extension to a paid application (SDK Paint), I have to keep some of the code proprietary so that Nintendo's own proprietary API doesn't get exposed.Perhaps we could make the API more publicised after the expansion?
If you are interested in connecting to the API that's used for the iOS app, let me know. I make it available for free on request.
