Just when I was about to give up all hope, I decided to try SoulSeek. And it works! I used to use SoulSeek way back in the day and always loved it. LimeWire works better, of course. But not if my ISP (the a-holes at DirecWay) are blocking it. So, if anyone's frustrated and has DirecWay, try SoulSeek. It works a helluva lot better when you donate (5 bucks for 35 or so days). Not too shabby. Better than not having a connection.
