I just noticed that the tutorials repo has no license. Oops! I suggest CC-BY. Technically we would need to ask all the contributors for their permission to put any new license on it.

Thanks, I never noticed! All the lessons were contributed for teaching purposes, so I don't imagine adding a license now would be a problem. CC-BY is fine, although we should also consider CC-0.
