assignments received by the FSF. Jason Thomas was added. Erich Stefan Boleyn was moved into those who assigned their copyrights. Gordon Matzigkeit was moved into the others, because he still wasn't listed in fencepost.gnu.org:/gd/gnuorg/copyright.list. The remaining problem is that we haven't had copyright assignments of VaX#8, Heiko Schroeder and Gordon Matzigkeit. As for the first two, Erich is now trying to contact them by proxy. So I'm just waiting. As for Gordon.... oh, what are you doing, Gordon?! Hurry up, please!
