I spent the entire time waiting for your video to get to the point, and I still didn't get it. The only thing I could get from the video, 3 and a half minutes of it, is that you like waving your mouse pointer around icons, and somewhere on the internet is a site that uses post icons for every thread.
For bonus points, I then went on to my own IP.Board 3.0.3 installation and created a thread with a post icon, so I could see if you did have a point.
You did not.
So, could you perhaps explain what your problem is, without Youtube this time? Because it sure isn't deprecated post icons (which are right... there...)
