LIMEWIRE OR MACTELLA???? NEW USER Needs 2 Be Informed-ERROR MESSAGES I am not real sure what limewire is and does,but I am wanting to learn and understand and be informed. Is Limewire primarily or exclusively used for music/audio? Sorry SO NEW. I could use a little insight into some of the nomenclature as well.

I've got a G4 500Mhz 56k modem basic connection.
LimeWire version 2.8.5
Java version 1.1.8 from Apple Computer, Inc.
Mac OS v. 9.0.4 on PowerPC
