I believe Molly is referring to the rights of the actual author of the article. Would the author be expected to sign away their copyright or exclusive rights, or would non-exclusive rights (perhaps under the licence you mentioned) be sufficient?

I've allowed people to use my articles before, but some of the places using them have since vanished. I would therefore be very wary about giving away exclusive rights, for fear of having my work vanish.
