I can't get to everyone, to show them what to do, but here's a crash course.
First option: go under message, you should see "block sender." Now if the
guy/girl is an anon you'll want a filter. For that go Tools and "message
rules." That thing is pretty straightforward, it gives you prompts, just
follow them. And if your newsreader doesn't have those options, contact
either usenet or webgeek. I began asking myself when did this become a forum
for dogs? I've had three, if I was still interested I'd have subscribed to
that kind of newsgroup and filtered a few out. Like puppychow, sorry
puppywizard, I just think I know who he is.
