Q: What are newsgroups? How do I use newsgroups? Got any info on newsgroups? What is USENET? What is Alt.Binaries.Music.SHN.DMB?
A: This has been described very well by a great Ant, Jay (Billie'sTV). This is a really great read if your interested in understanding and everything involved with newsgroups:
Alt.Binaries.Music.SHN.DMB - Quick Start (X-News)
Update(1-24-02): New Ant Buzzy has written a nice informative post on the subject too. Check it out.
