Jon has it right. We had a change in the cookie system - I think it was about 2000. There could bwe a name used before that date, that is used by a different person now. If it presents a problem, let us know - e-mail me, joe@mudcat.org; or Pene Azul, jeff@mudcat.org.
I don't think it should be much of a problem, since the change took back quite a while ago.
