Since I cant search, whether it be because im a lazy leacher, or because I cant find the button, I have found a new way that will work for now.
1.Begin to start a new thread.
2.Type in the key words you are looking for in the thread title bar.
3.Once it is finished searching, you can check the few it gives you.
Simple as that.
Worked for me when I was looking for the extended tab tageting thread.
