Bah, mics are pretty cheap now, just get a cheap crappy mic, or a headset, if you want to spend the money. gaming with mics is infinitely more fun than without.
Also, I still need to get a PERFECTLY LEGITIMATE copy of D2. But I rarely have torrents running often, because I'm either at school, where it's completely blocked (I need to set up an SSH tunnel.... :/) or I'm playing an online game and I want to avoid lag.
