Out of the 3 forums I'm a member of, this is by far the easiest and my favorite. If you get rid of the unread posts since last visit or new replies to your post option I and everyone else will riot!!
Lol I don't want to have to go to user cp and search around through a forum for these options. Maybe add a third one though that lets you select "past topics I've posted on" right there with these two on the front page so you can look at your old posts from the get go.
Also, when you click on home old cuda/challenger stuff should be on top. leave the off topic and new challenger stuff at the bottom because most don't care about it!
