@Dsouza,
Yes, they are confidential.
I've been here for years and years. This place arose some time after the New York Times Abuzz closed. The owner of this site and cohorts worked hard to make it accessible, without the faults of the NYT site, which was quite a zoo. Here there is free speech, though there are comportment rules (see the dark blue band at the bottom of your page.) This is a free site, a strong wish of the owner. It is a world site.
There are moderators, and you can contact them at Contact Us, see the same dark blue band below. Moderators are volunteers. I'm personally too grumpy to be a moderator, and strongly thank them for their pretty thankless time, and for the endless help.
I haven't looked at what a newbie sees when clicking on a2k lately, but I think there were choices to make that could be helpful. Look around.
