When I post from work (which I used to do, back in the days when we had internet access) it comes out as "guest." I am registered on my home computer.I generally like the silly threads, even when they're not music related. It's the same as sitting around with friends telling jokes in between the tunes.
I don't see any reason for people here to get nasty with each other. I really do think it's perfectly possible to have a civilized discussion about volatile topics and disagree with each other without flipping out.
