If you have the Simple forum option enabled, you will only be able to see a thread's title, page count, and author. By default, this is the forum option that will be selected the first time you view the forums.
To display additional information about a forum thread including the last poster, total number of replies, and total number of views, please select the Advanced forum option located just under the character panel in the upper-right hand corner of your screen.
