I live in a house with 4 other guys at school. We have cable internet. We all directly hook up our computers to the internet with wires. We don't have wireless internet. I am the only one that uses iTunes. And yet, what's this? Under "shared" in my iTunes I see "Courtney's Limewire Downloads" and "*insert chinese letters here*" and "Tim's Playlist." Does that mean someone's stealing our internet? How can I see them unless they're hooked up to my network?
