On your profile page, the Public Messages tab shows your personal message board. Any of your colleagues can post to it.
You can require the approval of these posts. This feature is known as moderation of the message board.
If you enable moderation, a CMS400.NET or group administrator, or the affected user must review and approve or deny posts before they are published. During that review, you can delete inappropriate posts.
If you enable moderation, the affected user and administrators see any new posts on the message board along with the previous posts. Approve and decline buttons (enlarged below) let them publish or remove the new posts.
