Exactly - our only way out of the license issues we currently have is to persuade the FSF to change it - a new license would apply to all *existing* articles without requireing an additional statement from the authors. However, if I remember correctly, we had some discussion in Germany some yeras ago that this particular point of the GNU Licenses (that the author license it's wark under whatever license the FSF will change it's current one into) would not be legal according to german law. I don't know if and how this was settled and if that's still an issue; I just wanted to mention that we possibly could run into difficulties here. But it's a very minor risk in my opinion, so it should not stop us from these talks with the FSF.
