One in the p2p world you only have five kings....
Bittorrent (not all clients are good)
edonkey (with sharereactor.com and filedonkey.com)
MIRC (just got to know which channel)
Shareazza.......useful if you have the right server list, but not something I would recommend.
IMESH, Kazza --- No.... just say No
If you must use the Kazza network try Kazzalite....but careful where you get the client from...cause companies are adding their stuff on these programs and sending out for you to download.
Wisdom is knowledge being put to use. Are you putting to use what you know?
