Because this is a Vista ng. However, I too am puzzled about why he would
not continue to use the private Vista newsgroups the TechBeta folks have
been using for a year. Unless of course he has gotten a TechBeta copy
improperly.
Having said that, this and the other public Vista newsgroups are not groups
for beta testing. It just happens that that is all there is right now. In
fact these are the public groups that will support Vista right through
release and for years beyond. It is the Techbeta private groups that will
shut down next year.
