You will find a button at the top left of the screen to seach the forums.  If you click that button, you will go to a screen where you can select which forums you wish to search, and what time interval you wish to look at.  click on the forum of your choice and time interval of your choice, and leave the search box blank, and you will get a view with the most recently replied post at the top, and it also shows the number of views on each thread.   It's interesting to watch how fast the views tick off during this time of evening...virtually as fast as you can refresh Machinery talk, there will be new numbers on the views of the top threads. 

Just an interesting tidbit.
