You simply have to ask them to sign the  copyright paperwork. Most people are willing to do that in my experience.  Stefan  My point isn’t that people aren’t willing sign the copyright agreement in principle, but that many people will not be thrilled to deal with a *paper* copyright agreement that they have to send via standard mail and wait for a couple of weeks to get back a response, just to get a tiny fix/change accepted. I think that GNU projects would benefit a lot from a contributor agreement that can be signed digitally. (Clojure’s development recently switched to digital contributor agreements and the number of people who signed the agreement skyrocketed). People hate dealing with paperwork and that’s a fact of life...
