CC by-sa 3.0 license for all of Bright Journey

Reference: http://www.brightjourney.com/q/licence-user-generated-content-bright-journey

We need to figure out a proper way to implement this with an API as well (no point of a CC license if other sites can't easily get the data out for use).

Here is what I think should happen (needs to be researched in detail on how to properly implement):

1. All SE questions have a byline at the bottom stating it's under a CC by-sa from SE.
2. All new questions that were created on Bright Journey have a similar byline, but slightly modified so that any use provides the attribution to Bright Journey.
3. Provide an API
4. Custom T&C that reflects the use of CC by-sa. Should state that any use of questions from the old SE site get attributed to SE, while usage of all new questions on Bright Journey get attributed to pages on here.
