Actually, the reason you are having such difficulties is because you are
using the dreadful web interface to these newsgroups. Since you are
using the web interface, you may not realize that this is really a
Usenet newsgroup. You will get far more out of this resource if you
learn to use a newsreader. There are many good newsreaders for Windows,
but you can use Outlook Express (XP) or Windows Mail (Vista) since you
already have it. Here are some links to information about newsgroups:
