Ok, when I try to download files from ppl, i'd say 65% of them don't work, they just time out. I keep getting this message - They and you are both firewalled, download not possible.

WTF, I am not behind a firewall. Is this a result of ppl leaching and not sharing like in napster? I think there should be no option to turn off file sharing, if you are not going to contribute to the community then you don't get to participate. Simple.
