Sometimes, you may want to sort the different topics in a forum by a certain criteria rather than chronologically (which is the default). But using this dropdown menu in the forum, you can change how those topics are sorted to suit your particular needs. The order can be ascending or descending by using the arrow dropdown beside the sort by dropdown.
Chronological (Default): In the chronological view, topics are sorted by the most recent topic created to the oldest.
Subject: The subject view will sort the topics by the title in alphabetical order.
Author: This will sort by the author's name, then in chronological order.
Replies: This will sort by the number of replies the topic has received
Views: This will sort by the number of views the topic has received
Last Poster Name: This will sort by the name of the last person to post to the topic , then in chronological order.
Latest Post: This will sort the topics by who has posted to any of the topics most recently.
