The forum sections themselves have nice [new] icons, but the threads don't. I find it hard to tell which thread is new, which thread has new posts etc :-(
Errr, no I think I get it now, just too used to other forums/themes I guess :red
It's easiest to just click on "Show unread posts since your last visit" or "All Unread Topics" http://www.masm32.com/board/index.php?action=unread;all
