#Wikipedia doing a #commercial project? Hell, why not! The license allows it and, it is wonderful outreach.
The Indonesian Wikipedia had a writing competition about theology. Publishers are interested in publishing and, the question is: can we do it.
In Commons we explicitly do not accept pictures available under a CC-by-nc license. This ensures that we have the widest possible audience for our material. It follows that the same applies for our articles. When a publisher or a website wants our material and publish it commercially they can. When they do it with us, even better.
