So, some recent discussion has raised a question in my mind, and just plain in general. A buddy of mine and I are thinking of starting up a small site for puzzles. He doesn't particularily enjoy computing, so I'd probably be handling all the setup and management while he wrote most of the puzzles. So, thinking into the future, if he were to write a puzzle and it was posted on our site, but didn't get enough attention and we wanted to then post it here, what course of action would I need to take?
Due to plagiarism concerns, I would want to give credit to him as I didn't write the puzzle. But, in doing so, I would be need to link the puzzle to a site that I would be associated with. What is an appropriate course of action in this case?
