I'm using OS X 10.1.5 with a cable modem. Been using Limewire for about 5-6 months now. In that time I've downloaded 400+ files, but have never uploaded one. I seem to be doing everything right as far as my limewire preference settings go, and file sharing is on in the computer. At one point I has 20gig of various types of Mp3, so it's kind of hard to believe that in all that time, NOBODY has tried to upload a single one of them?

Is this just a mac thing? An OS X thing? Or is there a third option I'm missing.
I don't really care that no one has uploaded any files, but I'm using the site, I'd like to at least be contributing.
