You can control what order topics (threads) and posts are displayed in.
The board default is to show topics sorted newest to oldest, and posts with topics sorted oldest to newest.
You can control these things in the User Control Panel (accessed from the User Control Panel link in the top left-hand corner of your screen).
Click the UCP link, then click Board Preferences, then click Edit Display Options.
This will open a form that allows you to toggle the topic and post sort criteria and sort orders. Set these up to make the board behave the way you prefer it to.
(Note that these settings are per individual user. Your settings won't affect anyone else's view).
