Why would there be a Vista newsgroup, it doesn't exist yet.
What doesn't exist? Vista is RTM. That means it's been Released to
Manufacturing. It's available to corporate customers. If it didn't exist
you wouldn't be asking about it, eh?
You seem to be imbued with pre-conceived notions. Vista has been in Beta
for a long time. The Vista newsgroups were created sometime ago for the
folks who were in the public CPP program through which they had access to
certain of the beta versions of Vista. The Vista newsgroups still exist,
are still public, going strong, and that's were Vista questions should go.
Notice the name of this newsgroup is microsoft.public.windowsxp.general.
You use OE to access this newsgroup. If you had checked the other
newsgroups to which you could subscribe on the same server you would have
seen the Vista ones, accessible both through NNTP (and the web interface).
