a. Do a search for it at www.newzbin.com, www.nfonews.com, or alt.binaries.nl
*** YOUR ISP CAN TELL YOU IF THEY HOST A NEWSGROUP SERVER OR NOT!!! ***
3. IRC (if you don't know how to use IRC, go to www.mirc.com and read the FAQ)
4. Search IRC at www.ircspy.com or packetnews.com
Helping out people is one thing, but when folks sign in here just to leach a D/L link or FTP is another. Don't do it unless you have every intention of sharing. Also, don't claim to have something that is not real. Joe made a real clear point on this a few days back. No proof, no thread. Period.
