When I visit the forums on the desktop browser and decide to come back a hour later, all the threads become read. Is there a setting to change it so that the thread becomes read if I actually clicked on it? There's a similar thread here about the app but it's quite old: http://forums.toucharcade.com/showthread.php?t=192250&highlight=mark+read
This is normal, Touch Arcade tracks the last time you logged in and will automatically mark anything before that time as "old" by only bolding threads with subsequent posts. I don't think there's any way to change it. When browsing the forum I usually just scroll down and look at posts by time.
