When you say all sub - fora (are you meaning to say sub forum?) should default that way, you mean last message first? It doesn't. I can honestly say when I set the filter to display "last message first" whenever I leave that sub forum and go to a different subforum, it will revert back to first message.Most Sub-Fora should default that way.
Which areas are you concerned about?
Those areas of the site won't display in that fashion.Ok now when I check the other forums, like General Shaving Talk, Straight Razors, and Everything Else they are set up to sort last message first which is fine, but Marketplace and the sub forums always revert back to newest thread.
I still want to be able to have the Marketplace forums all set to display newest message first, which was a hassle especially during the Black Friday period checking the Shopping and Deals sub forum and not getting the most up to date message without having to hit the filter button EVERY SINGLE TIME I revisited the site even if I stayed signed in.
