You can now set the number of posts you see on a single web page when you're viewing a topic, and the number of topics you see on a page when you're viewing the topic list. The default values are the same as the previous board-wide settings - 1000 and 50.
To change your setting, click the "User Control Panel" link in the upper left, then click the "Profile" tab. You'll see the new settings at the bottom of the page.
Another possibly helpful option for those viewing on mobile devices or getting web page updates via telegraph is to view posts in reverse order. Go to User Control Panel, Board Preferences, Edit Display Options, and set the post order direction to Descending. Just remember when someone says "see post above", it'll be opposite.
