What are you trying to do? I believe I replied to your other post asking
that same question. Set up a proxy server ON your computer, or set up your
computer to USE a proxy server? You haven't given us much to go on.
If you need to post to multiple groups, it's best to do so all at once in a
single message (separate the NG names with commas) so that everyone can
follow the thread. Thanks....
Crossposting = posting once to several newsgroups within a single message.
This is not a Bad Thing (presuming the list of groups posted to is small,
and all the groups are truly relevant to your question)
Multiposting = posting separate, identical posts to several newsgroups. This
is a Bad Thing.
