It appears there is a new editing function that allows corrections after a post is published on a forum. Am I correct? If so where are the instructions or if they are secret, will someone let me in on it?
You can edit only your own posts, of course. In the upper right area of a message (after it's posted), under the "Clippings" links, you will see "NEW Edit post". Just click that link and it will take you back to the familiar composition page that we've always used. After making changes, you again need to preview, like always, and then click "Update Message" (as opposed to "Submit Message").
