Gerry,
I use Blue Daze large font in the flat mode and even if I don't read all the threads with new posts, I can go back later and they are still in blue. If I don't pay attention to how many new posts there are, I sometimes will miss new posts if there is another page that I didn't see. You can also try the link at the bottom of the Main page "View recent messages Past 24 hours" so you won't miss any new ones.
