Thanks all. Particular thanks for posting how precisely we can get to this setting; took a while to find it!
I've set it to Category & Latest, but when I click on the logo in the top left I still see just the list of latest posts. I had expected that clicking the logo would bring me to "home page". I'm very new to Discourse, I'm not even sure I'm leaving this feedback in the right place.
Thanks again all, love your work!
