To give players greater control over their forum browsing experience, the new World of Warcraft community site now supports Simple and Advanced forum views.

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.
