I just want the home page to land on it. I already have the Latest tab do what I want thanks to the setting for “desktop category page style” “Categories and Latest Topics (sort by topic created date)” but you have to then click on the latest tab in order for that order to appear. When you just go to the home page it shows the old order by activity even though the Latest tab is highlighted. Actually, I also noticed that every time I click on the Latest tab it toggles back and forth between home (straight url) and yoursiteurl/latest?order=created.
Anyhow, looks like the best option is to redirect my home page to /latest?order=created
