When I click on say "Mazda 6" option to view the threads for Mazda 6, I cannot select to view them by most recent date . My only 2 options are by Thread Name or Thread Starter. Those 2 selections go alphabetically up or down (reverse). I don't have a Thread Sort selection by date.
It use to do by date, but I no longer have this now.

 

I clicked on column "Last Post" to sort by date.
However, it does not remember my last setting and defaults to style like Post 1 "Thread" not by "Date"
Once you click on a Forum you want to see. IE : "General Tech", click on it to see all threads in it. Now go to column near top labelled "Last Post" and it will change the order to what you need and it will display a down arrow on that column. It's just one extra step at the end.

 

There are "Display Options" for Threads at the bottom of the page that you can change your view. However, the defaults are wrong and when you change them it does not remember them when you change from Mazda 6 to Mazda 3 (for example).
The defaults are "Thread Title" in "Ascending" Order.
The defaults should be "Thread Start Time" and "Descending"
