When you are viewing posts with replies, scroll down to see a place to set your comment viewing preferences. "Comments" are replies to any forum post or blog entry. The options are:
* Threaded — Displays the posts grouped according to posts and replies.
* Flat — Displays the posts in chronological order, with no threading.
* Expanded — Displays the title and text for each post.
* Collapsed — Displays only the title for each post.
You can also choose how the comments are displayed, by date, and how many comments are displayed per page. After you finish, save your settings, and the comments (replies) will reflect your choices.
