People: If you really insist on using a mic:
1. Don't let me hear the game on your side. This drives me nuts. When I'm streaming this means I hear sound FOUR times.
2. Don't say anything. I can't hear you anyways.
3. You know what? Just don't use the mic.
Last night I kinda got fed up with hearing someone's game and just unplugged my mic from the stream, plugged it into the PS3, hung it on my speakers, then kicked the guy after he said some sort of stuff that I didn't hear or understand yet again.
I felt kinda mean, but I put up with enough, I think.
