I use the "New Posts" menu, when I'm on my laptop (and signed in). You can bring up a query with new posts from one day to a 2-week span of time. Then, just scroll down the list & see what interests you. Sometimes I use the "Active Topics" query.
I have noticed, however, that it depends on how you access the forum:
Laptop Browser, not signed in: "New Posts" will only display one day's worth
Laptop Browser, signed in: "New Posts" query can range from one day to 2-weeks worth
Android Cell Phone Browser: If not signed in, no "New Posts" option
Android Cell Phone Browser: If signed in, "New Posts" will only display one day worth.
I think that some people use an app on their phone to view the forum. I'm not aware of what the options are with that. I just know we are not all using the same method of accessing the forum, so we don't necessarily all have the same options available.
