I was told this by someone on the IRC.
1. Find your IP address. A good source for this is here.
2. Visit http://youripaddress:1214
* substitute "youripaddress" for your IP address.
* http://localhost:1214 will NOT work.
3. Make sure a KaZaA Lite is connected. And select the file yo wish to share.
4. Right click the file, select "Copy Shortcut".
5. Done! People can click the link and they will download the file that you are sharing in KaZaA Lite. (Remember to keep it running).
