I'm gathering this is related to the maintenance... I noticed a few changes like new icons for each main section, but also it seems "Mark this forum as read" is gone. I still see "Mark all forums read" on the navigation bar, but I clearly remember being able to mark an individual forum as read using the links on the right hand side between the threads and the nav bar. Maybe it's just me? I need to reboot? Logoff and back on? I doubt I'd be the only one to notice this.
