Basically right now, the same people who could delete posts on the old software.

Moderated messages are just a service to people and reflect the opinion of the moderators. Some people don't like this, so you can ignore the moderators and see them anyway.

There's a deleted mode (which only a couple of us can do) and a moderated mode.

Deleted is only used for duplicate posts (which shouldn't happen as often) or something very bad.

Moderated is what will be used most often and it will be used a little bit more than before.

You have the choice to see the messages you would not otherwise see if you didn't have the "Show Moderated" option selected.
