To be blunt, what the hell is it?

My girl's older brother is one of those hackers who never leaves the house. Hell, I've never even seen the guy wear pants. He mentions pulling things off of newsgroups, and the last time I got a crack from him he mentioned something about a program called newsleecher. Got it, I'm a pretty software capable person, I figure I can stumble through it until things start making sense.

So now I've got it, what do I do with it? And what the hell are newsgroups anyway, I've been jumping forums all afternoon and haven't found anything for a newb of my level, and I really don't wanna ask my brother in law, he still doesn't like me too much
See Jane. See Jane run. Run b*tch, run.
